The Slackware folks have it working, but non-systemd distros are going to need to find a desktop they like and work on it, same will apply to wayland. If a distro doesn't want to use modern Linux tech they're going to have to put in the work.
I've already passed along the Slackware patches to our GNOME maintainer and he wasn't impressed. And that's about all the effort I care to expend, since I wouldn't be caught dead using GNOME. It's not for me.
That's fine DE's are personal but the larger point is those distros that don't want to adopt new tech need to start creating and maintaining the things they need to operate. The contradictory path is hard for a reason.
Can you say why you wouldn't be caught dead using GNOME?
Just don't like it. There's nothing inherently wrong with it but you won't catch me using it. If I was personally more invested in GNOME then I'd put some effort into getting it to work on Artix. But alas, that's got to be someone else's cross to bear.
I used to use gnome, but I moved to XFCE when switching to Artix last year. I must say I think I like it better. I still get to use a convenient desktop that looks GNOME-ish, uses GTK, has a bunch of theme options, and is a lot more lightweight than GNOME without requiring systemd. It seems like the best of possible worlds at present, although I've wanted to try out a tiling window manager like dwm for fun. I'm not sure I'd be able to get used to/comfortable with using one as a daily driver though.
It's technically possible to get GNOME 49 working without systemd, but it's merely kicking the can down the road.
The reality is that work has to be put in to support non-systemd paths. If nobody does that, well it has to be dropped.
If opensource were generally paid, there would surely be devs working on non-systemd support in GNOME.
