The feature freeze is distutils is not a conspiracy plotted by developers loving purity; it is a necessity caused by hard pragmatism. Tarek would have loved to continue improving distutils instead of forking distutils2, but he could not because third-party code relying on bugs and workarounds was broken. We have to be cautious, and it has nothing to do with purity. Believe me, the freeze, fork and merge was not something fun for distutils developers, but we had to do it precisely for our users.
While I agree that in an ideal world, “'python setup.py install' should be all a user has to do on any platform”, it cannot be done in distutils. Like Martin said:

For distutils2/packaging however, we can work on improving the compiler system, so that “pysetup run install” is all a user had to do on any platform. See #12257 for that.
