What is a type ontology? The definition of ontology I'm familiar with
is too broad to be useful in understanding what you're getting at.
I've never heard the technical term "type ontology".

If I guess at what you mean-- a fuzzy notion that the underlying type
system can support both languages-- then I submit that most of the
hard problems are indeed here.

Not quite sure what you mean ehre.

I think you mean memory management in general, not just GC. Others:
thread model, interpreter management (such as creating embedded
