Interesting idea.

I'm not sure, if I fully understand the quanta syntax. I'd assumed that
something like x(-30:30)(0:0) would not allow any movement, as you
suggest. But it is still movable as if I'd use plain x (without quanta).
When I use something like x(-30:30)(-1:1), it jumps between -30 and 30.

Unfortunately, when using quanta, the variable doesn't return the input
(my mouse movement), but the result. So the number jumps between -30 and
30 as well.
