> And yes, most distributions use Xorg by default and all attempts to switch to Wayland fail, ex. Ubuntu. (maybe GNOME is an exception, but it's probably the only DE where Wayland somehow works).

This is just false. Wayland's the default in Ubuntu, Fedora, Debian (how many users is that?) etc. And it works just fine out of the box on Gnome and KDE/Plasma, the two big DEs.
