Anyone interested in "package versioning"?

I’m a bit puzzled by this discussion… 

Packages are only namespaces and have zero information about semantic protocols. I’m thinking about analogies from OCaml and the ancient COM/OLE interface system. Those examples provide versioning regarding semantic capabilities of a module, and versioning is important so that usage gets tied to a compatible library module. But namespaces are too thin to provide any of this sort of protection.

Seems like the discussion needs to address a module / interface system in Lisp, which does not exist to my knowledge.
