Review Comment:
BTW a comment like "moving the ..." is only pertinent as a code review
comment but not as a comment in the code. It's a verb pertaining to a change
that a commit/PR makes, which generally makes a poor/weird comment (similar to
what I said in another feedback here today). I'm not sure I'd bother with this
comment. If we are concerned that someone might add a call to
getCollectionRef above the lock, then we could add a comment up there to warn
against making remote calls without holding the lock.
