One step at a time. Right, that paper doesn't introduce life-shattering innovation but rather just fixes a long-standing issue with UDP performance in the Linux kernel. That ain't nothing. A large motivator to develop and deploy QUIC is that by implementing much of the stack as a userspace library the protocol can be iterated on at a pace impossible with TCP. BBR congestion control experiments are a great example of that; there's enormous value in quick iteration, even at the cost of compute efficiency. I agree with your sentiment though; I have to imagine eventually the protocol will settle down and hardware acceleration will become a thing - but imho not to the degree you propose.
