The idea is not discarded afaics, KSystemEventFilter still exists and
can be used (but should be used with great care as it gets all events
and hence can interfere with arbitrary applications on the desktop).

Yes, at least the logout dialog too (I've filed a report for that one)
and according to Michael Jansen also various desktop effects. IIUC
basically anything that tries to grab X11 keyboard itself interfered
with kglobalaccel (which does the same to handle global shortcuts),
because kglobalaccel suddenly saw all X11 keyboard events from all apps
and thought it might have to handle them.
