TCP is basically exists to deal with an unsolvable problem, "the two generals" Its easy to look at it and say it could be better because you have tunnel vision for your use case. However its also easy to forget that the protocol literally has a billion edge cases. Why do you think your NIC has a new driver update every couple of weeks even though they have been running the same protocols for the last 50 years?
