No, I misread the intent of that part of your message

Sounds good.

Personally I would want to live in a world where we don't *have* to nor
*want* to support submodules without .gitmodules in the respective
superproject.

We did support some use cases historically that I would make sure to
continue to support, but I am not sure how much effort we want to spend
on supporting further use cases of incomplete submodules.

Feel free to do so, as such tests help to document the boundaries.
