This isn't a new bug, but it's exposed by always importing weakref and atexit during interpreter startup. I'm wondering if that's really necessary :)

Importing it during startup isn't necessary per se; imports needed only by the generic function implementation can and should be imported late, rather than at the time functools is imported.

However, if pkgutil was/is migrated to using this implementation of generics, then it's likely going to end up imported during startup anyway, because at least the -m startup path involves pkgutil.

In short, the overall answer right now is, "maybe", and the answer later is "rather likely". ;-)
