GNOME 41 released

Quite, yes.
Plasma does not (to my knowledge) has an ability to run arbitrary unsandboxed third-party code inside its display server process, so it has an easier task here.

(What particularly amuses me about the whole {Gnome,Wayland,X} (x) {RedHat,Xorg,FreeDesktop,Gnome Foundation} and the respective {hierarchies,priorities,bug trackers} is that it's basically the same handful of folks with one main source of funding. So maybe, I dunno, don't rush the X deprecation before Wayland is actually dependable?)
