Even then, my statement holds true, just with different numbers.

Every distribution modifies upstream in different ways, I think it's insane to
do contortions which will break things for people *not* getting things through
those channels. If distributions are going to modify one upstream project they
should expect to need to modify things that depend on that project in ways that
are sensitive to what they've modified.

The only real sane thing IMO is for openstack to consider requests as it is on
PyPI. If openstack wants to make it easier for downstream to de-vendor urllib3
from requests then when openstack wants to import from requests.packages.* it
can instead do:

    try:
        from requests.packages import urllib3
    except ImportError:
        import urllib3

This will cause it to work correctly when requests is installed in a pristine
state, and will fallback to handling the modifications that some downstream
redistributors make.
