This ended up with more "Also..." than I had anticipated... They're however
fairly easily recognizable. If you think it's ok to land the three bits as one

into their own CLs.

I'd prefer this to be split, if it's not too much trouble.

Ping back when this is rebased against those other changes...

Rebased on top of the two split out CLs. PTAL.
