That's the wonderful thing about xkbActions.c. The filter system has to
be rewritten, too - it needs per-level granularity. Maybe there can be a
more general approach towards canceling actions when doing that.

But maybe you would want to put the focus on switch-group-on-release
first. If want to try it without Press/Release knowledge inside the
handler you might want to try to skip the first event. If that works
together with an option to select between when to trigger the switch
(press/release), that would be an improvement already.
