The proposed change has the effect of reducing the effective Window if ACKs are compressed. Say you have a window of 12 packets, acks are delayed, and a single ACK acknowledges 12 packets. Now you have a window of 12 packets, your transmission rate is 6 times slower than before, and it will take you 10 RTT to recover. Is that really what you want?
