That would not begin to describe it. Indeed, I am not recalling any discussion to the effect that Interval would be changed along the lines you describe. It would be, in my opinion, a bad idea. The reason is that it would take reasonably fast functionality and make it quite slow, and would require techniques that are not necessarily reliable. That's not what interval arithmetic is meant to do.
