I have kind of gone silent on this issue, in part because I have been busy with other things. I think that Charles Harris' framework for working with polynomials is perfectly sufficient for adding Chebyshev polynomials, and since they're finished and working and fill a concrete need, they should probably go into numpy or scipy as is. But if you want to start introducing other types of polynomials - Hermite, Lagrange interpolation based, Bernstein based, or other - I think we would need to revive the discussion about how to unify all these different types.
