AFAIK the name/path mapping was added to enable moving submodules around in the work tree without having to adapt its $GITDIR/config entries every time you checkout a commit where the submodule's work tree is moved someplace else inside the superproject's work tree. Nowadays we also use that to consistently store the submodule's .git directory under "modules/<name>" inside the superproject's .git directory no matter what its current path is.

You still don't need a .gitmodules file to use submodules locally, but then moving around these submodules is not - and has never been - that easy. To use the ignore setting without a .gitmodules file you'll just have to set both submodule.$name.ignore and submodule.$name.path (to provide the mapping, in most cases path and name will simply be the same) in your $GITDIR/config and everything will work just fine.
