Well sure … anything, like lattedock, that is abandoned/discontinued or simply incompatible with the new libraries due to a current lack of updates et al … will be broken.
Thats known and technically true for any software on your system.
( and has virtually nothing to do with wayland )
I suppose you can wait as long as hermitly possible to see if any of those things you ‘need’ get revitalized. But thats not exactly advisable either.
How sure are you that you actually ‘need’ any of those things?
In whatever case … such discussions are not for this thread.
