You would lose a lot of roll stiffness which would have an adverse affect on the handling.
Without the rebound spring there would be nothing to stop the main compression spring unloading on the inside wheel which would in effect jack up that side of the car and increase the roll. (i.e. reduce the roll stiffness)
The ideal is to have the 2 springs perfectly matched which is relatively easy on a nice known smooth race track but is quite difficult to achieve on unknown bumpy normal roads so a compromise is needed to get the best average handling.
The problem is that different drivers will have differing opinions on what that compromise should be.
Very difficult to get a one size fits all solution on the road which is where some adjustability comes in. ( If you know how the system works and understand what effect the adjustments will have.)
