In such a top-level project, people would not use "git submodule"
command, would they? I do not think anybody in this thread was
pushing to forbid such a use, and it may be perfectly fine if "git
submodule" does not work for such a gitlink; after all such a
subdirectory is not even meant to be a submodule.

I am not sure if I agree with that direction.
If the trend in Git community collectively these days is to make
usage of submodules easier and smoother, I'd imagine that you would
want to teach "git add" that was given a submodule to "git submodule
add" instead by default, with an option "git add --no-gitmodules
sub" to disable it, or something like that.

I agree that a feature like this is needed regardless of what
happens at "git add" time.
