Ah, right -- this patch is actually derived from the previous one, and it is simpler. That older patch became a bit outdated since some of its changes were split out and already landed in main. I found it easier to start fresh with a new patch rather than rebasing the old one.

That said, if you’d prefer to stick with the old review (to preserve the initial comments there), I can force-push this patch to the old review instead.
