Well fixing the code to hash based on UUIDs was not so straightforward
so the easiest was to update the docs to match reality. All of the current
callers always provide a non-NULL name & UUID. When someone gets time we
can still make it hash based on UUID instead, but until its done I think its
better to have acccurate docs to avoid confusing people using it and then
wondering why they get a SEGV on a NULL dereference.
