KDE got some kind of video bridge recently which is an insane workaround for something that should've just worked.
You're worried that capturing Wayland screens from X11 applications requires additional software?
How is that a real complaint? The only way this would be possible without additional software is if Wayland itself was just another X11 Version, if Wayland was X12 which is X11 but with protocol changes that break backwards compatibility, you would run into exactly the same problem.
Your standard for something being insane is that it is not 100% identical to X11.
