They seem to be using setuptools commands here:
https://github.com/numpy/numpy/blob/master/numpy/distutils/core.py#L48
https://github.com/numpy/numpy/blob/master/setupegg.py

I think that they are responsible for installing the f2py script in
each of my Scripts directories. I never use this script and I don't
know what numpy wants with it (my understanding is that the Fortran
parts of numpy were all shifted over to scipy).

I guess this is what you mean:
https://github.com/numpy/numpy/blob/master/tools/win32build/cpuid/test.c

Is there no way for them to run a post-install script when pip
installing wheels from PyPI?

Maybe. I'm not usually on their mailing lists but I'd be willing to
find out what they think. First I need to be clear that I know what
I'm talking about though!
