For numpy that seems fixable (if it even breaks, it may not). As long as
the setuptools maintainers are willing to keep numpy.distutils
compatibility, I'm happy to make the necessary changes in numpy.

FYI, it has happened twice (IIRC) in the last five years that a new
setuptools release broke numpy.distutils. This was fixed very quickly with
good collaboration between the projects.
