I won't die without one, but it would be nice. It may also be that an
existing perf test, but I don't think we cover partial clones in t/perf
at all. Might be worth just a straight-up "git clone --filter=blob:none"
test.

Also, in the proposed merge message above, it should be --filter, not
--depth, right?
