Why isn’t documentation with appropriate red warnings a suitable place if we really must have it? That sounds like a much better solution that some weird function people monkeypatch. It gives them more control over things (maybe they have a valid certificate chain, but an invalid host name!), it’ll work across all Python implementations, and most importantly, it gives us a place where there is some long form location to be like “yea you really probably don’t want to be doing this” in big red letters.

Overall I’m -1 on either offering the function or documenting it at all, but if we must do something then I think documentation is more than enough.
