I guess it is related to this:
https://review.openstack.org/#/c/6847/

Maybe per-release compaction would be better, but that doesn't help
those deploying close to trunk, and makes it tricker with stable
banches (but I think we leave a few numbers for that kind of thing).

What is the plan now we are in H? Compact all the G migrations into a
single set?
