Ah, that changes my view of it significantly. If the authors want to
contribute it to Python some day, I'm looking forward to that (assuming
that they then close their official branch, and make the version inside
Python the maintained one).

That is also independent of whether standard library modules get written
in Cython. I would expect that some may (in particular, if they focus on
wrapping an external library), whereas others might stay what they are
(in particular, when they are in the real core of the interpreter).

I would personally prefer a Cython integration over a ctypes one, for
the standard library (and supported inclusion of ctypes into Python
