I think it could have other effects - it will impact the robustness to loss/congestion on the return path compared to the way TCP operates. Sending one isolated ACK here isn't the same, although you could argue that the ACK information is indeed repeated "ACK Delay" or "N packets" later. If we relax the number of packets per ACK this may need a little more thought to avoid delaying congestion detection when there is loss?
