Thanks, the split did make things easier to understand.

These all look reasonable to me, and I confirmed by re-running a few of
the problematic perf tests that everything is behaving as expected after

I think this is reasonable, especially with the feature in patch 6 to
tell the caller they're doing it wrong, instead of just silently
