Comment (by yawning):

 Hmm even if you make txsocksx optional there still needs to be code for
 handling Twisted versions that don't have
 `twisted.internet.error.UnsupportedAddressFamily`.  Instead of in
 `__init__.py` this could be done in `socks5.py` since that's the only
 place that uses that exception.

 Since it's just error handling, we could also change the code to sending a
 SOCKS5 General Failure error for `EAFNOSUPPORT`, but that seems less
 optimal for people that do have recent versions of Twisted.
