You are correct but don’t forget that somebody’s swing app broke and they’re real salty about it.
Also I can’t speak for whatever you’re worried about but when I moved to Wayland the only thing that broke was java shit like Matlab and those closed software companies are not going to fix their shit for Wayland unless they have to. Oracle certainly isn’t going to do shit unless forced. It’s not open source anything holding anything back.
Things have changed in the last year or so. This is about the next releases of distros, nobody’s going to go back and retrospectively remove X11 and Xwayland will continue to exist when needed.
All the hubbub is because Gnome recently decided to drop support for launching X11 sessions from the login manager. Gnome’s login manager is Wayland based and Wayland handles handing off graphics to different users properly. With X11 you have to have ugly things like killing the login X server and then spawning a new X server as the new user among other things is ugly and unfixable without serious security issues.
Wayland wasn’t stuck with design decisions that made sense almost 50 years ago in the '80s and does things far more sanely and with less complex code.
Anyway at some point someone has to pull the plug and Gnome has done that. Many distros are built on Gnome so that’s that.
