I tested the following example:

import ipaddress, mmap

x: ipaddress.IPv4Network[int]
y: mmap.mmap[int]

MyPy produces errors: error: "IPv4Network" expects no type arguments, but 1 given error: "mmap" expects no type arguments, but 1 given

This is because mmap and IPv4Network are not generic types in typeshed. _BaseNetwork and _mmap are generic types, but IPv4Network and mmap are normal classes. The former are implementation detail of typeshed. _mmap does not exist in the stdlib, and _BaseNetwork in typeshed and the stdlib are different things.
