This appears to be a concern for some people. Maybe the builtin ssl module should be deprecated if there isn't a lot of manpower to maintain it and instead the well-maintained pyOpenSSL package should become the recommended tool?

Here is a letter that I just received, in my role as a developer of Tahoe-LAFS, from a concerned coder who doesn't know much about Python:

Here is my reply to him:
