I looked at that function and saw how it was using the relatedness
heuristic, but I'm still unclear what fs operation needs this metric
in order to function. (Something to do with replacing a directory
entry, of course, but I don't understand precisely what and why.)

Apologies if this is documented in structure and I just don't remember

I guess I'd like to take a harder look at why the fs layer has to
figure this stuff out in the first place. Presumably it's some
ramification of versioning directories that I just haven't thought
through yet.
