If you're software is older than 20 years, then you had to deal with this same issue ~20 years ago.
ie. it's a non-issue... do the work and update or don't. That's your choice.
Wayland is only slightly newer than X.org - and it's been on the horizon for years and years already. If you haven't updated by now, then you made that choice.
The folks maintaining X.org know there are issues that cannot be overcome without a major re-write and protocol change. The change has to happen even if it was a X.org v2... and you would still be complaining.
also the x12 protocol has the same wayland concept on mind, so wayland is x12, and xorg developers are the one working on wayland, who is better to know how hard is to maintaing the software than the same mainteiners?
