I am sure it was not.  

If adding a separate worktree only for one submodule, you should be
able to "cd $path-to-submodule" and run "git worktree add" to create
a new worktree, and I do not see any reason for the superproject to
get involved in that process.  Does it have more information ready
than the end user has to help the process of creating a new worktree?

While I can understand how --for-submodule above may be implemented,
I do not see the point of adding such an option.
