The reason why there was no mention is probably because no one
intimately familiar with Cython was there, and if they were - it was
not brought up. If Cython supports PyPy - and Jython, and IronPython,
your proposal makes sense. The reason for "pure" python implementation
is so that other implementations can share the exact same standard
library we have today. I don't see adding a cython version as helping
that.
