Did you consider that maybe when you hold an opinion different than the people actually knowledgeable about a topic - like the people developing desktop environments and the former developers of X building Wayland - it might be because you are wrong and have a poor understanding of the field and not because they want to annoy you?
The flaws were not limited to the 1996 poor security extensions. These kind of half broken extensions are everywhere in X11. At some point, if the tweaks you have to do is basically rewriting the whole rendering pipeline and adding new APIs for the most significant systems, what you are doing is strictly équivalent to writing a new piece of software which is exactly what the people behind Wayland did.
And don't worry, the change adverse people you see here complaining about limitations fixed years ago would be complaining the same if the effort was on rewriting part of X11. That's life. Armchair complainers and keyboard warriors will complain while actual doers push things forward.
