I assume you mean "you might want to keep all of the subprojects' objects 
in the same git object directory".

And yes, that's absolutely true, but it's technically no different from 
just using GIT_OBJECT_DIRECTORY to share objects between totally unrelated 
projects, or using git/alternates to share objects between (probably 
*less* unrelated repositories, but still clearly individual repos).

So the main point of superproject/subprojects is to allow independence 
(because independence is what allows it to scale), but there is nothing to 
say that things *have* to kept totally isolated.
