Demanding that all drivers always stop at all yellow lights effectively turns the yellow light into a red light, and drivers are forced to switch instantaneously between "go the speed limit" and "stop."
I don't know about where you are, but here amber lights mean "Stop if it's safe to do so", i.e. if the choices are go through the junction or slam on the breaks, you should go through the junction. If the choices are to stop smoothly and safely or go through the junction, you should stop.
