yes, I’m working on it (in free time)

I guess that the main issue here is that scipy and numpy do not provide binary wheels for Python 3.9 which has been released yesterday. It would be really nice to have wheels for Python 3.9 so not many users trying the new Python would not have to compile scipy from sources.
