The way the rules are written, if you have a setup so that when you steered left a servo stiffened the right hand side springs, whether you are crawling around a tight hairpin or going flat out round a banked sweeper, then at the moment there's nothing to stop you doing that at all. Although it is fairly pointless as you can get similar actual handling just with springs and roll bars.
Adding in the receiver throttle signal as well would also lead to some interesting handling characteristics as the throttle signal is not dependent on actual speed at all. Lets say it is set up so that it only stiffens the suspension when steering and when on power. This is great for a sweeper, at speed it stiffens the springs and keeps the buggy flat at high speed. But you then have a slow, tight hairpin so you brake and turn in, the suspension remains soft and the chassis rolls, until you open the throttle halfway through the corner and the outside suddenly stiffens. Unless you are going to feed in the throttle very slowly it's going to lead to some interesting handling out of slow corners.
Of course tapping into the motor sensor lead so you can measure the actual motor speed using the motor sensors is already banned in the current rules.
Then there's the problem of adding all this extra complexity and extra weight into a buggy, with none of the extra weight likely to be able to be placed in the best places for weight balance. Realistically it's not going to make much difference on track but would be an interesting engineering exercise. If someone does fancy a go I would say the best way would be 4wd axles and a diff or spool in the middle with the brake disc attached so less unsprung weight and no trying to balance left and right side braking. Good luck on trying to match it to the progressive braking on the rear though.
Years ago I did know a fellow racer who tried experimenting with a third servo controlling the rear wing which he mounted on a pivot so when he braked it raised to stabilise the rear end, but then flattened when accelerating to reduce drag on the straights. It meant he had less steering going into a corner and less rear grip coming out of the corners. He tried swapping it round so wing up on the straights but flattened when braking which gave him much more steering into the corners, but when jumping if he braked to lower the nose it also flattened the wing and ended up landing upside down.
