The entire series looks good to me:

Looks like that s/that/than typo ended up in a few spots throughout
this series... Nothing major, but figured I'd bring it up.

Pondering how to stage this, both for later upstream but also for
testing. Would probably make the best sense to stage 1-5 separately,
and then just punt the remaining ones to the appropriate subsystems.
And then 12/12 can go in when they have all been applied.

That's frustrating. Seems like an email setup problem on my end. I'll
split this series up and resend.
