The flip side of that is end to end encryption, which pretty much ensures that "a bit is a bit". And we sre seeing most of traffic being encrypted, pretty much armored against shenanigans in the middle. Given that, stuff like SRv6 is mostly useful for traffic engineering, which seems like something we would want.
