Regarding this, you can look at the source:

odd = M % 2
if not sym and not odd:
    w = w[:-1]

so it is implemented  in Scipy, explicitely limited to even windows. It is
not in Numpy, though (but that can be fixed).

I think a reference is worth adding to the documentation, to make the
intent and application of the sym flag clear. I am sure a PR will be most
