Well there are still commits, but in the superproject the UX feels more
as if the submodules were special trees. So if you want to interact with
the submodule specifically, you could do things like

    git add /path/inside/sub
    # works seamlessly from the superproject tree

    git commit --submodule-commit-only
    # When the flag is not give, you may get an editor
    # asking for two commit messages, (sub+super)

    git fetch --submodule
    # When the flag is not given, we'd fetch superproject and
    # on-demand

    # You feel the superproject is in the way?
    git worktree add --for-submodule <path/to/sub> ...
    # The new submodule worktree puts the
    # submodule only UX first. so it feels like its own
    # repository, no need for specific flags.
