Interesting, that question would probably have gotten a different response on scicomp, it is a pity we are not attracting more questions there!
I know there are two polyfit modules in numpy, one in numpy.polyfit, the other in numpy.polynomial, the functionality you are suggesting seems to fit in either. What parameters/functionality are you considering adding?
