There's no need to change the longstanding defaults, because it would break
things.  You already have a knob you can tweak if you think that "2 a / 3 b"
should multiply by b, rather than divide by it.  That's a personal choice.

Frankly, I'd never touch that knob, because it looks to me like it should
divide by b.  And I think most mathemeticians would agree, and that's the
target for that part of Calc.  Stop thinking computer science.  Think
*math* notation.
