Lower latency for video demand means that I can stop/rewind/scroll with less
annoyance.   We saw this in the demos that showed up at IETF hackathons a few
years ago.

Customers are *not* demanding that, because:

a) they don't know it's about latency.
b) the end users experience the pain, not the netflix/disney+/etc. people
c) it's hard for CDN people to actually do anything about last-mile bloat.
