I'm pretty sure nobody has seriously proposed making this change
in a non-major revision.  I suspect anyone who might have implied 
that would say they weren't really thinking at the time they said 
so, and that of course if we went ahead with such a change it would
not cause code breakage in existing code until a major revision 

I could be wrong about this though...
