But, the G02/G03 is known to be a single move, so there is no velocity change until the end of that move. NURBS doesn't really solve this problem, it just condenses the description of the surface, and allows a program to fairly simply determine the accelerations that might be needed to traverse it.
The problem with general G-code is each block tells you nothing about any other block. So, you have to read arbitrarily far ahead to know if there are any sudden changes in velocity coming up.
