One thing that this misses (as does your original script) is the
reflogs. Doing "branch -m" to rename a branch will actually move the
reflogs, too, but there is otherwise no way to access that
functionality.

It does not seem unreasonable to teach "git update-ref" to do renames to
take advantage of this (it would be fairly simple; the logic is already
encapsulated internally in a rename_ref function).
