And I personally need kicad - it doesn't support Wayland at all because of some mouse-related stuff. Again, Wayland team thinks it's not their problem.
Then I had a lots of issues with a graphics tablet. Yes, it's a cheap chinesium knock-off, but it does work on X11. Wayland - no chance and it's obviously not their problem.
So I dropped Wayland altogether and went to X11/herbstluftwm. Was a few years ago, but I didn't bother to go back since - why should I? These aren't their problem, but now I don't use Wayland anymore, so these aren't my problem either.
What I'm trying to say, "hundreds of thousands of gamers stress-testing" have very little to say about usability. Yes the graphics part is excellent, nobody is denying that. There is more to a WM then graphics.
Do you? Not going to lie, I'm perfectly happy just using the apps I want to use and having none of them talk to each other. 90% of my use is covered by Vivaldi (browser stuff which is most stuff these days) and Kitty (Neovim, random TUIs and utilities). The few other apps I have are Steam, Krita and Blender, which are all worlds unto themselves and have no need to integrate with anything.
