Yup, makes sense.

I think we should rather say "object ID", as "oid" is an abbreviation
that might not be immediately obvious to the user. Also, should we
continue to mention the object ID? Otherwise it might be hard for the
user to figure out which object ID doesn't exist in case they pass
multiple refspecs.
