Oops! Could you please help us by hinting how the documentation

I do not agree, as they'll be seeing a new option and might use
it to "go backward" as Junio explained in his answer.

I don't understand that. How is that different from using different
names (and thus different separate gitdirs) for that duplicated
submodule? After all, the .git directory is just moved somewhere
else in the superproject's work tree, and as the name defaults to
the path of the submodule ...
