If we relax things too much, will we also get homebrew and macports and built-it-myself pythons, and will they work?

Not likely. On 10.7 and 10.8 python.org and system python use llvm-gcc while IIRC homebrew used clang. There's probably more differences.

So the question is:

If someone is running a brew python and does "pip install numpy"  will pip find a binary wheel that will then not work? That would be bad, but maybe not our problem -- brew users should be using brew to build numpy anyway. 
No that is not how homebrew works. Brew does not pack anything that pip installable: https://github.com/Homebrew/homebrew/wiki/Homebrew-and-Python
so that would be a big issue. Especially since installing numpy with pip and brew python just works without any problem when building from source. 

There are unofficial brew taps (channels) with python packages but this not the recommended way.  

It would be nicer if it didn't happen, though.
