I think your patch is a sane thing to do.

Once reflog entries begin expiring, we won't have the null_sha1 on the
previous side of them, and after that we will keep returning the
oldest-known one, so nobody should be expecting to find out when a ref was
first created in this repository by checking with what timestamp that
syntax breaks in the existing interface.
