Although, TBH, just restoring the original behavior with head requests
seems like it would be significantly simpler.  And for me personally,
where I live in StrangeWorld where renames are extremely expensive
(essentially copy + delete), would also be a lot more efficient.
Looking at the other options, I do think restoring the original
behavior is the best one.
