I agree that issuing a warning and continuing is best. If the submodule hasn’t been setup
then we should respect that and keep the current behaviour (just archive the directory entry).
There is some further debate to be had about the extent to which this should work with
un-initialized submodules which I’ll discuss in other replies.
