We don't want to go back to distutils-only; there are some advantages to
setuptools and it's gotten less bad at breaking numpy.distutils over the
last years. And anyway, even if we would switch away from setuptools, pip
will enable setuptools before calling our own setup.py and at that point
setuptools has already done its monkeypatch-distutils dance. So there's no
point avoiding setuptools.
