Before your patch, when you create a ref refs/heads/foo/bar, then pack
refs, then it is impossible to create a ref refs/heads/foo because
refs/heads/foo still exists as directory. And this is a good thing.

With your patch, is there any mechanism that inhibits that refs/heads/foo
is created when directory refs/heads/foo does not exist, but a packed ref
refs/heads/foo/bar is present?
