Fair enough, let's work together to find a solution here. Out of
curiosity: Wayland is not shipping in a distro thus far (as far as I
know), what is KDE's /kwin's integration model there? Do you get help

Great, feel free to point people into my direction and we can get
started as early as next week!
Looking forward to it and thanks for starting the discussion. Do you
need anything else from my side to get the conversations going?
