Not sure I understand: could you explain a bit or if you haven't done it 
yet point ot relevant code?

Naively, I had always though that interface were frozen as soon as they 
were 1st committed! So in that perspective I very much agree not to 
change it.
But if we don't change it *and* don't introduce a V2 version, what shall 
we do then? ;) I'd go for V2, the differentiation code will probably be 
ugly and a pain to read (if, instanceOf and cast) but I see no other way!
