@mirjak pacing may be implemented and controlled outside of the transport. I have two new concerns about text around bursting packets on network:
1. Many CDNs and edge deployments will tweak IW to be a higher value. In Windows TCP we allow config of up to 64 MSS. So if the network admin knows what they are doing and can swallow bursts then we shouldn't discourage the practice. 
2. UDP segmentation offload is reality now and for high throughput flows using hardware offload to reduce CPU will mean larger bursts trading off against pacing. We shouldn't preclude this either.
