So Plasma6 X.org has less graphic tablet settings, right?
Plasma 6 xorg might have the X11 KCm which is the most featureful configuration frontend for graphic tablet on linux. It is on par with windows and wacoms utility. KCM on wayland is not so much.
I would call that a regression and not a wishlist? You can for sure ask to tag those issues correctly.
I had changed the severity once but it was reverted back and then other discussion about this was not entertained you can check the bug reports see the comments marked as spam.
People will make the switch is there is no issue. See how pipewire switch happened. I am not adamant about maintaining the status quo. By forcing people you are just punishing them for no fault of theirs. It is not like they are sticking to X11 because they are X11 fanatics. Give these people working alternative and they will switch in a blink of an eye.
It is always easy to say these things when you and your work is not affected. Tomorrow these people will switch to something else and say your computer is not bootable or for some reason you are not able to do your work due to that change will you say yes make the change I am happy?
