I have a small reroll that I'll send shortly which contains a minor
fixup and one new patch on top.

I'm assuming that the "uses tb/cruft-packs" is related to the two topics
both squatting on t5327's real estate? If so, feel free to eject the
cruft packs topic for this cycle, and we can look at it again after
2.35.

Otherwise, the version I am going to send is based off of dcc0cd074f
(The sixth batch, 2022-01-03) in your tree, so it should apply cleanly
onto master without the other topic.

Thanks,
Taylor
