Drop the ‘Steam’, it's cleaner. Wayland's raison d'etre is to push frame buffers without tearing. Input is an afterthought.
This. You need more than graphics to have a windowing system. Wayland team threw out X11, did graphics and left the rest for the others to figure out.
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.
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.
