I'd settle for your earlier slightly porous formulation, at least for
one go round. We don't seem very fond of hard and fast rules as a
community (c.f. txid controversy) :-) The target should be to get to
beta within about a month from feature freeze, I think.

Maybe we need a better triage at the start of feature freeze which gives
candidates a preliminary review, at least enough to say "this is/is not
very close to being able to be applied". Anything that isn't, even if
submitted well before freeze, misses out. If reviewers are more active
then the candidate list would be small.
