history traffic patterns show clearly a rising in-equality/ power-law distribution. so unless that multi-year (decade) long trend reverses, forwarding lookup hierarchies are going to work even better.

That's for bandwidth. You're still screwing low volume connections.
Consider 1 million people watching netflix from the perspective of a transit provider. If you're just looking at bandwidth you can obviously prioritize lookups to netflix servers. But then you have 1 million streams to different client IP addresses throughout the Internet. Each on its own will be a small fraction of the bandwidth, so are you going to punish them all? Not much gain from lookup hierarchies there.

netflix caches are serving millions of subscribers using a thousands to ten-thousands of prefixes, well below 100K.
their caches are highly regionalized so its no practical problem.
