Well, I meant wayland-wayland, not wayland thru Xwayland. I'll keep Xwayland, and those horrible 748397438924 client libs (yeah wayland code is static/private to distributed binaries), for games still missing a wayland backend (with unity/unreal5.x/godot/etc and via libSDL[23], I wonder if that exists on modern elf/linux games unless a custom engine).

But it seems the really hard part for valve is dropping their 32bits legacy code which is hardcoded for x11 and opengl... they are adamant at keeping it.
