Hmm. Either I want the revert in before the release, or your series
to make the merge window (and hence probably hit in first couple of stable
releases).

Ideal would be revert very soon and chase it in to togreg so your series
can go on top, but that would rely on some lucky timing of pull requests
and merges that is probably too optimistic.
