Perhaps this is because I've never needed or played with "prepared
transactions"; but to me a commit is a commit is a commit. If it isn't in
the product, then whatever it was was not a commit.

That order seems partially backwards to me. If someone needs to glance at
a patch and say "That whole idea is never going to work" or more
optimistically "you need to be making that change in smgr, not lmgr", it is
probably not going to be a novice reviewer who does that.

Sometime this type of high-level summary review does happen, at the senior
person's whim, but is not a formal part of the commit fest process.

What I don't know is how much work it takes for one of those senior people
to make one of those summary judgments, compared to how much it takes for
them to just do an entire review from scratch.
