C extensions are like a black box for lot's of python only developers. 
You have to understand python, C and cPython to understand a c 
extensions. Also you can't use pdb or similar python tools to debug a C 
module.

I understand it's a PITA to maintain both implementations. On the other 
hand it's very handy for developers like me who like reading code to 
understand implementations.
