For new features I completely agree, but for old features we have to be 
really careful about not adding redundancy, IMHO. Events are used quite a 
lot and the new constructors did much more than just make the API 
consistent -- it also made it way simpler, to the point where what was 
three lines of code with dozens of ambiguous arguments is now a single 
line of very readable code. With the canvas objects it's not at all clear 
to me that we'd get the same win.
