It would be nice if a redirection via a "gitdir = ..." line
in .git/link of the subproject (when existing) would be possible.
This was part of the light-weight checkout proposal.

In contrast to contrib/workdir/git-new-workdir, this would allow
for (to be implemented) magic symlinks to stay intact when
moving the submodule directory around.

However, this can be added later.
