E.g. for one-off web page design it’s been good enough for a long time.

In just the last two months, I've been handed the following web projects:

• A page filled with bootstrap style div-soup
• A page filled with tailwind style class-soup
• A slideshow webapp that has duplicated state and three different ways to change slides (navigate(), goTo(), and changeSlide()).
• A slop-grenade of a chatbot interface for navigating a user through a flow chart, documentation of the flow chart, and documentation of the logic of the flow chart, all of which conflict with each other.

I think the effect you’re seeing is that different people have different levels of “good enough”

I think the effect that I'm seeing is twofold:

1. People don't realise that every line of code is a liability.
2. People think that once they have something on the screen that looks finished, the project is finished. They haven't thought about support or maintainability at all, and since they are completely inexperienced about such things: they aren't qualified enough to when when a project is "even done", let alone "good enough".
