In my opinion, there should be even less stuff in numpy. If I had my 'druthers,
linalg, random, and dft wouldn't be in numpy either.

The problem is that this argument is the same for just about *any* scipy
package. There needs to be a better reason to place something in numpy.
Otherwise, we will end up with a numpy as bloated and difficult to install as scipy.

If you want to ameliorate the problem, the way to do it is to work on scipy's
packaging such that each subpackage can be built and installed separately. We're
not very far from being able to do that.
