I'm still buried after Plumbers, but one of the bits on my TODO list was 
to look throught the new definitions for frozen and stable.  Nothing in 
this extension life cycle talks about the point at which compatibility 
will be maintained, which was really the central point behind frozen 
before.

Are there more concrete definitions somewhere?
