What kind of crops are you going to grow at 125°? That's still within OP's specification of triple digits and with temps getting hotter we're likely to see a lot more of this happening within our lifetime.
Yeah I think there's some good ideas that have been built up with the ABL devices over the years, and that mesh leveling seems great. However I also feel like more people should take the time to get their beds physically as flat as possible first, because otherwise your printer spends a lot of time micro-stepping the Z, and I've seen some mesh maps that looked absolutely horrible.
Playing around with arduino devices, I have some laser rangefinders that seem like they could work well for an ABL. That might also be a good way to map out the idea I mentioned about creating a thin full-bed shim to get a truly flat bed, and after that perhaps you would only need to do a fast four-corner calibration with the ABL to make sure nothing has changed.
I've never had auto-leveling on my own printer, but the one at work has it and I wouldn't want it. It was great for the first couple years, then the sensors started suffering from corrosion and now it just doesn't work for crap.
So on my own printer (fully manual) I have always treated the paper test as nothing more than an initial step to make sure the nozzle doesn't plow your bed during the leveling process. It will get you close, but not close enough. To really dial in your bed, you need at least a 5-point 1st-layer print test so you can really get that initial layer adhering nicely at all points, and this of course performs the calibration with the bed at full heat so it matches conditions during actual prints.
The biggest problem I had was my aluminum bed was badly warped when I got it, but fortunately just bowl-shaped. I cut CD-sized discs of aluminum foil to build up the center -- 13 layers in total, then put a glass or G10 bed over that to really get a flat surface. I finished mine with a PEI sticker on top of the G10.
Another problem is that all beds will be completely unique from each other. I have one of the original Ender 3 Pro printers, and purchased a Creality glass bed with it. There was nothing that wouldn't stick to that bed, and I used a 10mm calicat (which has 4mm feet pads) as my tests for all new filament. Clean the surface occasionally with 91% ISO, and life was good... but after a few years the surface wore out and I was forced to get a new bed. Ordered directly from Creality again, and man, nothing at all would stick to that piece of glass, even for large prints. I tried everything down to brake cleaner to solve the problem and finally gave up on it. That's when I started working with the G10. The point of this is that you can tell someone a particular bed will solve all their problems, and you will be wrong. The reality is that sellers use different manufacturers to make their product and you never know what you'll get.
Your observations about the bed warping from the tightness of the screws is interesting, I never thought about that part before. I have heavy springs under my bed, and I have always suggested people get those springs as tight as possibly without being completely closed, then adjust the Z-switch to that point before you start your leveling process. Tight springs means the screws should never wander. It's been around 3 years since the last time I even touched my leveling screws, and I just fired up the printer and ran some new pieces last week without any issues. A good tool is one that you can ignore for a year, then use it without having to recalibrate. Anything else is just frustrating!
There are a lot of suggestions we can make to help newcomers get their bed leveling correct, and there are a lot of variables that we simply can't account for including manufacturer defects. One idea I had years ago but never got around to trying is to print a thin sheet of filament the size of the entire bed, ironed to create a top surface perfectly flat to the nozzle but taking up any imperfections in the aluminum plate. Then put a thin bed over the top of that, and you should have a perfect surface that lasts nearly the life of the printer. Seems like a good idea, but how do you figure out where to fill in those first layers until you have a final layer that covers the full bed?
God that article was a horrible read. So for anyone who wants to skip it...

Wouldn't want the snowflakes feeling bad about their natural tendencies, would we?
This started on Wednesday, almost immediately after Trump's victory was announced. By Friday it was already being reported in grade schools because asshole parents enjoy raising asshole sons, and Trump tells people that it's ok to be the absolute worst human being they can be.
I have a friend who is a hard Republican. We generally don't talk politics, but after this started last week he was posting things online being offensive towards women and POC (and the whole "illegals took my job and healthcare") so I finally had to call him out. His response was basically that he wasn't aware of any increased discrimination happening against women, therefore he didn't believe it was happening. I've known the guy for 40 years but this may be the thing that breaks our friendship. He claims to be an advocate for people's rights yet he is painfully unaware of the world around him.
Didn't Ukraine give up its nukes specifically under the condition that Russia would leave them alone as a free independent nation? Seems those terms went out the window years ago.
Don't forget that Musk is also the one who intentionally blocked paid service from Ukraine during a critical moment in the early days of Russia's current genocide, because Musk sucks up to Putin. Dude needs to answer for his actions.
Don't forget that Amazon also routinely charges shipping costs that sellers have already rolled into their pricing. The first time Amazon moved away from the $25 free-shipping mark, I started looking elsewhere and found the same sellers at their own websites or on ebay, with zero shipping charges (I was looking for hard drives at the time). When I reached out to ask the sellers about it, they said they had no idea Amazon was up-charging their orders but they had no say in the final pricing.
Now that Amazon has once more abandoned the $25 free shipping I have stopped using them entirely (again). I'll read the site for product reviews, then go find the same seller on ebay and get it for an honest price and free shipping.
Literally nobody ever believed it was about "protecting the children." This was never anything more than a cheap shot by those with low and questionable moral value to force everyone else down to their own level in the swamps. Anyone who tells you they are doing this "as a proper Christian" are the same kind of people who are so morally bankrupt that they can't even tell you what it means to love thy neighbor without looking up the words in their favorite piece of fiction.
I'm afraid there's nothing new about this, it has been going on for a long time. What I do believe is happening is now that every idiot with a cell phone can jump of sites like lemmy or reddit, we are simply seeing a lot more examples of the problem. Pretty much like when camcorders became affordable to the general public, we suddenly saw all kinds of police brutality videos and some people thought this must be a recent trend when in fact it had been occurring all along.
