Digging deeper there are mechanisms for long time on internal X side (see https://www.x.org/releases/X11R7.6/doc/xorg-docs/specs/Xserv... ) - granted never seen it practically implemented.

And going to rabbit hole there are even proof of concept security implementation named Xnamespace for Xorg fork (needs polishing and much more patches but looks doable. see wip documentation: https://raw.githubusercontent.com/X11Libre/xserver/d2b60a3d6... )

The way X11 developers ended up fixing this is by creating Wayland. This way privileged operations (like keylogging, screen capture, etc) require the cooperation and authentication through the display server.

That sort of solution is cancer if you want to do anything the display server authors didn't think of. I've got a script that I invoke with a global hotkey that determines the window title of the currently focused window and fuzzy matches it against pipewire audio stream names so I can mute the focused window with a single keypress. If I want that to work in Wayland I'm pretty much up shit creek because somebody with their head in the clouds thinks that my needs are super dangerous or something.

That way you also prevent things possible in X11 to be impossible in Wayland, like a window setting it's own position, if you were to want that.

X.org developers, not X11 developers.
