This should no longer be true. Our downstream redistributors pointed out to us
that this  was making their lives harder than they needed to be, so it's now
our policy to only  update to actual release versions of urllib3.

Per my note above, if we restrict ourselves to relatively recent versions of
requests  (2.7.3+ IIRC) we should be fine. Of course, that doesn't mean we can
actually do that...

It should be assumed that approach number four is a non-starter. This list has
had that  conversation before, which was a stunningly unpleasant experience for
me and not one I  want to repeat. Additionally, getting *all* of
Fedora/Debian/Ubuntu on board with not unbundling requests is about as likely
as hell freezing over.
