Screen color calibration, no nvidia support (not their fault, but that doesn't solve the problem, does it), HDR (KDE has it in beta, but no one else does)...
I'm sorry, it's an unfinished product (unlike, let's say PipeWire, which is why it was quickly addopted). X.org devs went 180 regarding development of Wayland vs X.org. It had a bad foundation to begin with, not enough supported protocols... everything after that is just patching the obvious.
They should have ditched Wayland 15 years ago and start from scratch when they saw how poor the standard was regarding protocols. If X.org was too big and heavy, Wayland went in the complete opposite direction. A middle ground should have been made, and adoption would have been quicker and more stable.
Or you just lay in bed at night and just try to properly edit the score notation to a song you really like, but it's kinda niche, still all your friends know it, and then brag about it when you meet up "yo, check out my ringtone π" π.
And not just Lemmy, most of the Linux user base.
