Supporting both could be double the work for unpaid volunteers which may not be in the organization's best interest.

Also in python programming the pyautogui module only works with X11.

AFAIK XWayland is still supported, and pyautogui should work fine in XWayland.

Edit: Nevermind, thought it was some gui framework, it's more like xdotool.

As far as I know it's not even possible at all in Wayland to make mouse and keyboard automations.

You can, you just can't use the X11 tools, because it's not X11. Look into ydotool for a universal option, or there's kdotool for kwin.

Also the stylus in some Thinkpads is only supported by X11.

Use an older version of Plasma, or ditch Plasma.

I'll stop my recurring donations to KDE. If they can't support me, I don't see why I should support them. Their resources are limited, true, but so is my money. It's best donated to initiatives I have use for.

you could switch to different DE of course but u can also keep plamsa for wayland and use something more lightweight for X11 thus giving your games more resources and RAM
