You're certainly right in that the guarding is entirely superfluous on wayland, but grabbing still "works".
Despite the platform window ::setKeyboardGrabEnabled() returns false for wayland, QWidget simply ignores that and assigns the grabber.

What's worse: looking up the Qt code, QWidget only maintains the grabber as static variable, the grabbing state is never re-tested.

Eeeewww... this is gonna be more complex, I fear.

I wonder whether the grabbing state can actually be tested except by approaching a grab from a sidearm process. In doubt, the only possible hardening would be to continuously - and the only test whether it worked would be to invoke QWindow::setMouseGrabEnabled(bool grab) as well.

Stay tuned ;-)
