Hm, yes, that would be nice. Then multi-mode commands like
`quit-window' could have a complex predicate that does the right thing,
while very mode-specific commands like `gnus-summary-catchup-to-here'
could have a simple (mode-only) predicate.
If these predicates become very complex, then `M-x fooTAB' would become
exceedingly slow, though...

Yes, but modes could be converted gradually, and things would get better
and better as time passes...
