If you have an object with a del method as a module global, the cyclic gc will refuse to consider the module globals at all (which means it will affect unrelated objects).
So, yes, I think the shutdown purge is still necessary. Perhaps there are ways to make it smarter.
With my earlier suggestion a module deleted from sys.modules before shutdown can have an unreclaimable global dict (if it contains a global with a del method).
Perhaps, instead, modules could use a weakrefable subclass of dict for their globals dicts. The module destructor could save the global dicts of deleted modules in a registry. At shutdown any remaining globals dicts can be purged.
