wayland dwms can and do absolutely implement that. For example kwin has a setting to let programs access keyboard input in the X11 way for the old method of global shortcuts. And to disable the framebuffer for fullscreen games.

If you wanted, you could probably write a wayland compositor that has all the X11 apis that old management tools use. Wayland is just an api at the end of the day.

Users do have choice, X11 still exists, there’s lots of distros to choose from, but Wayland is the culmination of 40 years of learnings from the X11 project.

Linux hosts with desktop managers/window managers were loved by security testers and threat actors for how darn easy it was to get spyware running - logging all keystrokes, recording the whole screen, etc. X11 gave all apps the keys to the kingdom regardless of security policy.

Wayland is vastly more secure. Sure, there’s work to be done to build out a few edge cases - they’re known and have been in discussion for years at this point - it just takes time.

X11 had 40 years, Wayland had only had 18. With most mainstream distros switching display server, we should have the remaining sticking points ironed out in the next couple of years.
