[SciPy-Dev] pull requests and code review

Fair enough.   API users willing to review are golden.  I am happy to suppress my impatience to give users time to see changes.

It makes me wonder if one could set up a system that allows downstream users to voluntarily register to receive notifications on changes to functions or classes that affect them.  

Functions that are heavily used would have more time for people to review the changes.
