This is true of *any* new API. Whether this particular innovation is
worth trying is perhaps arguable. But I don't think there's really
much question over whether innovation in general is worth doing, and
you can't do a new API without exactly this kind of backward
In this case, furthermore, the innovation has already happened and has
already made it into application code - that's what started the thread
off. So doing this wouldn't even be innovating!
