The wheels-based system knows a disable flag:
https://github.com/chaoflow/nixpkgs/blob/python/pkgs/development/python-wheels/wheels.nix#L44

I think black-listing python versions means less work than
white-listing. I guess most packages break either because of not
supporting 2.6 anymore or not supporting 3.x, yet. Once we flag that
properly, adding a new python version is unlikely to break a package.

Wit white-listing we would need to add it to every package.
