I remember using an SGI workstation around 1992 which had a perfectly usable and complete X11 desktop environment, which according to Wikipedia was 5 years after X11 was released (1987), and 8 years after the X Window System was invented (1984).
Wayland has been in development for 15(!) years, has a much smaller scope than X11, and it's still a hot mess. I doubt that the 1980's programmers were so much better or more productive than the programmers working today on Wayland, which in turn means there must be something fundamentally wrong with the basic idea or design of Wayland?
Basically, moving on to an X11 successor should be a no-brainer for all Linux desktop users and not require one justification blog post after another why some things don't work anymore as they used to.
