The module itself does not create much work. But its tests are a regular source of pain and instabilities. The tests for nntplib depend on external NNTP servers. These servers are sometimes down, very slow, or don't work over IPv6. I'm sure that Pablo and Victor can tell you some war stories. I briefly mentioned the issues in the PEP, too.

The section in audioop was confusing. I have updated the audioop paragraph and the crypt paragraph with your feedback. I'll keep the PR https://github.com/python/peps/pull/1063 option for a couple of days to collect more feedback.
