You could be making a repo that mirrors all of the refs, but has a
different HEAD (e.g., the upstream has "development" as the main branch,
but you want a local mirror with "production" as the HEAD).

I agree it's an unlikely combination (which is probably why nobody has
complained about the weird behavior), but I don't see a particular
reason to forbid it.
