X11 and everything around it is unfixable security hazard slop, just slop that was painstakingly created by humans.
Also Wayland is it being forced on us? I have plenty of coworkers that run X daily because they are still afraid of the Wayland boogeyman despite the fact that their supposed clipboard and screen sharing problems in Wayland (the only two supposed problems they can name) have been solved for years.
People don't use Xorg daily because they are afraid of wayland. People use Xorg daily because they have tried wayland and there was something that stopped working.
Xorg allows running sub-instances.
Wayland is now older than Xorg was when "it was really old, we need something new".
