Well, my understanding was that new instances of modules was created
and that the communication between modules
was the "functional" communication of the outer module that uses the
submodules to work.
What other kind of communication we are thinking about supporting?

If we support statefull modules, sharing the instance of (private)
submodules is going to have unpredictable behavior and/or breaking
encapsulation.
