Alternatively, we can record SHA-1 in the shallow file as refs whose name is always ".shallow". This way "unbundle" can recreate the shallow file if it wants. Having this "remote" shallow file would fit well in our fetch pipeline. It's harder to recreate shallow file if we record prerequisite instead: if commit A is in the shallow file, the ones in prerequisite category would be A's parents. So we would need to go over the bundle to look for commits whose parents are all in prerequisite list.
