Yes.  One problem is that it's very hard to get a patch reverted.  Tom
opined that too often patches roll along toward commit and that it's
too hard to say "no, we want that".  But that's nothing compared to
how hard it is to get a patch reverted.  It's true that, if Tom calls
for the revert, it more often than not happens, but nobody else can
really pull that off without a major war.

And, you know, I did my time fighting major wars to try to compress
the release schedule, and honestly, it wasn't that much fun.  The
process we have now is imperfect in many ways, but I no longer have
abuse heaped on me for wanting to boot a patch out of a CommitFest.
That may be bad for the project, but it's spared me a lot of grief
personally.  I think that many other people are in the same situation.
Everybody would like somebody else to be the schedule enforcer ...
unless they have something that they still want to get in, in which
case they would like nobody to do it.
