The Python ssl module is used for servers and clients. Ideally servers will
have prefer server ciphers on, but that doesn't always happen and providing
a modern level of security for end users is preferable.

These are not things that affect only paranoid people and expecting someone
to even know what OpenSSL is much less how to configure it and what they want
to configure it to in order to get modern levels of security is backwards. The
danger for breakage here is *tiny*, *miniscule*, almost non existent and the
failure case is obvious and easy to fix.
