rmapbt will remain EXPERIMENTAL because I still have more patches to
send to finish the feature for realtime devices.  Speaking of which,
it's now been 53 weeks since the last dump of that, so I'll go do that

FWIW I /also/ run rmapbt everywhere and haven't had any trouble with it
since adding the per-AG reservations.
