While you did sign up to review one patch in the last CF, the amount
of review you did for that patch is surely an order of magnitude less
than what WARM will require.  Maybe more than that.  I don't mean to
point the finger at you specifically -- there are lots of people
slinging patches into the CommitFest who aren't doing as much review
as their own patches will require.  I'm putting a lot of time into
reviewing patches this year, and basically none into writing my own,
but I still can't review every major patch that somebody submits.  I
can't even do committer review of all of those patches, let alone
first-round review.

Perhaps I ought to rank the things I review by descending order of
importance, in which case this arguably ought to be pretty high on the
list.  But I'd feel somewhat bad working on this instead of, say,
multivariate statistics or unique joins, which have been pending for a
lot longer.  Anyway, the point, not just to you but to everybody, is
that the review can't always be left to other people.  Some people
will review and not contribute any code, and that's great.  Some
people will contribute code but not review, and to the extent that we
can support that, it's also great.  But the giant backlog of
unreviewed patches which has accumulated shows that we have too many
people needing more review than they produce, and that is not great.
