Right, I don't disagree we should have smp and gmp 'just in case'
(fine names as well) labels, I just don't really understand why you'd
trust something enough to grant gmp but not enough for smp...
Particularly encouraging people to grant gmp as though that was 'safe'
is really bad advice.
Which in turn makes me wonder why the umad dev node label is not
sufficient.
