More that if a protocol has met it's limit and you are at a dead end it is better to build a new one from the ground up. Making the internet faster is great but you eventually hit a wall. You need to be creative and come up with better solutions.

In fact our modern network infrastructure returns on designs intended for limited network performance. Our networks are fiber and 5g which are roughly 170,000 times faster and wider since the initial inception of the internet.

Time for a QUICv2

But I don't think it addresses the disparity between it and lightweight protocols as networks get faster.
