not sure about the flip, but let me break some things down a bit for those
who don't know:

what pip has internally already (i.e. literally in it's package namespace):
- pypi crawling/downloading
- wheel installing (does not require the pypi wheel project; only building
wheels requires that)

what pip has "bundled' already:
- distlib (in 'pip.vendor'; currently only used for some --pre version

what pip still needs to be self-sufficient to do wheel installs:
- something bundled or internal that does what pkg_resources does

theoretical options:
1)  bundle setuptools/pkg_resources
2)  use the bundled distlib to replace our use of pkg_resources
3)  internalize pkg_resources as pip.pkg_resources (i.e. fork off
