Imo it's good to check that things are consistant with whatever assumptions
have to be true, if the hash gets corrupted somehow, we'll at least get a
warning that things are not in order. Most arguments to public/semi-public
APIs are sanity-checked this way.

Well, it hurts in the sense that it has a runtime cost, which can be
non-negligible when these checks are run in a tight loop, but I don't think
these specific functions will be called that often.
