The usual open-source approach is fueled by people who enjoy
reinventing the wheel over, and over,...

I have a hard time reconciling this statement with the previous.

And if it's a bad choice, can we blame you for deflecting valid
criticism in favor of a wait-and-see approach?
The question is not so much whether Cython should be used, but rather
to what extent. I have expressed concern that writing hundreds of
thousands of lines of Cython code (as SAGE has done) is potentially
dangerous. On the other hand using Cython as a wrapper generator
carries little risk and might represent an improvement over SWIG for
It's irresponsible to continue promoting an unproven technology like
Cython without first addressing these concerns. Furthermore, it's
profoundly ignorant and extremely offensive to argue for replacing
existing implementations without first making a solid case of the
deficiencies of the status quo. This sort of fanboyism causes people
like me, who help maintain an existing part of SciPy, to treat Cython
