     * To maximize similarity with how the `git submodule` command behaves, we treat the SubmoduleWalk as canonical and the content of the .gitmodules file as tertiary.
     * However, that may change.  There's a lot about MdmModule that doesn't work without a .gitmodules entry anyway, so if it's faster to start from that list, we might as well.
