Well, but there is a need for a common object traversal.
You need that when sending all objects between two supermodule versions
and also when you determine which objects are still reachable.

The easiest way to implement the common object traversal is to have all
objects in one object repository.

It may be possible to use two object stores and still do the common
object traversal but I do not think that gives you any benefits.
You still don't have a totally separated repository then, because
you can't do a reachability analysis in the submodule repository alone.
