ISTM the most natural way to publish a "known good" commit hash is by
updating a branch head to point at the latest good version. In fact
this is pretty much the exact use case that motivated the invention of
DVCS back in the day :-). Unfortunately hg makes this a little
trickier than it could be, because in hg the same commit can't be in
two different branches; but this just means you have to insert some
no-op merges, oh well.
Interestingly, this is almost identical to merge gating (at least, if
I'm correctly guessing what you mean by that -- the "not rocket
science rule"?), just with different names for the branches :-).
