I'm not quite sure what "it" is, here. If "it" is that there be no 
incompatible changes in Python: this is not policy, and not even
consensus. Instead, policy (as enforced by the release manager), and
consensus is that bug fix releases (2.x.y) must not show incompatible
behavior. For feature releases (2.x), incompatible behavior is 
acceptable (at least this is what I thought consensus is, but
apparently I'm wrong).
