I think one of the biggest problems of Wayland are the "non standard, but kind of necessary" extensions.
E.g. screencapture. Does Wayland support screencapture? Yes (kind of), but I can't write a Wayland screencapture app. I need to write a Gnome screencapture app or a wslroot screencapture app, or I can even write one that supports both.
But what if someone using the new Future Desktop Environment wants to use my app? It probably won't work because it probably will use a different extension for the same behaviour. So I need to add the extension for that too...
