Yeah, but that does seem much more transport-y and low-level than
authentication and proxying.

Well, the choice I was discussing was that between reimplementing the
stuff like urllib2.HTTPBasicAuthHandler using httpx (which I guess would
require some refactoring of httpx), OR just reimplementing
urllib2.AbstractHTTPHandler using httpx (ie. replacing HTTP / HTTPS with
whatever class(es) from httplib / httpx).  You're suggesting the latter,
obviously.  There's no equivalent issue for urllib, I guess.
