X11 offers at least accessibility. The wayland team, to me, seems to be hyper-focused on reducing the duties of a GUI system to only providing basic interfaces. They didn't care about usability, accessibility and practicality, and they are currently (for the last few years) trying to pay this off.
Even more problematic is that X11 lacks user-noticeable deficiencies. Architecturally it has (partially severe) issues, but as an user, you don't notice. But if you're blind, need a screen reader, or want to use software enabling you to interact with the desktop environment outside of the classical, expected hardware (mouse, touchpad, screen), you're still out of luck. At least, screenshots mostly work now.
Yeah I know, probably unpopular opinion.
