I think one answer is because distutils doesn't have defaults that play 
well with eggs.   NumPy provides very nice extensions to distutils which 
will correctly add the include directories you need.

Look at any of the setup.py files for scipy for examples of how to use 
numpy.distutils.   Once you convert your setup.py files to use 
numpy.distutils there really isn't any problem anymore about where numpy 
puts its include files and the benefit gained by being able to use 
versioned eggs is worth it.

Yes, the transition is a little messy (especially if the build is not 
using distutils at all).    But, numpy.get_include() really helps 
mitigate that pain.
