I don't think we need this any more than if pip was not pre-installed. So still nice to have for things like chef but not a requirement. setuptools and distlib won't depend on pip, pip will just bundle them (like it already does for distlib).
The idea should be that pip itself has no dependencies because a package manager with dependencies is kind of strange and can easily lead to issues where the package manager breaks and is unifiable (e.g. setuptools breaks and pip can't be used to fix it).
