I realize there are quite a few retired PRs in this space.

However, the current system sets up perverse incentives. If I want to maximize my throughput given a certain congestion window, the optimal behavior is to always send ACK frames in their own packets.

IMO, simply not counting ACK frames in flightsize (and the header of ack-only packets) is conceptually cleaner and a pretty simple change to the implementation.

If there are no objections I can file a PR.
