I've now tested this; I added an elpa submodule in a straight emacs
clone checkout, and in a worktree created from that clone. There is only
one copy of ELPA in the emacs clone repository.

You have to update each worktree now; updating the submodules should be
done by the same command that updates the worktree. If there is no git
command that does that directly, we need to write a shell script; that's
certainly possible.

Changing each submodule to the next release branch will be done in
emacs/master/.gitmodules by the package developer; I assume that will
propagate everywhere.
