There's no fundamental objection to Cython, but there are practical ones.
a) Most of NumPy isn't Cython, so just having Cython gives us little. b)
Is the NumPy on Cython house in order? AFAIK part of the MS project
involved rewriting parts of NumPy in Cython and modularising Cython for
targets besides CPython. And that this was *not* merged. For me to be
convinced Cython is a good target, I'd need belief that there's an interest
in it being a common platform, and when I see that there's work done, by
core developers, which sits unmerged (with no timeline) I can't have faith
