Legacy classes in a module

Regardless, I think we still need to distinguish whether the legacy classes
should be considered module private (use case #1) or made visible externally
(use case #2). I don't think we can really know the developer's intent by
looking at the legacy classes alone. Even if rewriting is involved, we still
need to distinguish these cases in order to have the proper export
information in the superpackage.
