The current thinking among deveopers is that new modules should be 
written and maintained in Python, which all implementations can use, 
with speed-critical parts written in C for speed and imported by the 
Python code.

You can write a PEP offering Graphine. To be accepted, there would need 
to be some evidence that is the best Python graph module avaible and has 
some community support.

I would probably use it more that 90% of the stdlib.
