I was answering the specific question of GP: "Why can’t you do this with a TCP connection? Just measure the time deltas and throttle yourself if it spikes, right" which wasn't limited to head of line blocking but more precise handling of transfer-rate of packets. Still, TCP is controlled by receiver so if you have a have on both hides you might be able to do what GP suggests, but you'd still pay the jitter of sender buffer and the noise of fragmentation of your messages.
