By the way, I don't think NIP-65 is a solution to anything or even required to solve anything. It is just one nice addition to the model. It worked already before without that, relying on NIP-05 relay hints, nprofile codes, relay hints in events and keeping track of things.
Watch this relatively old video, it is very enlightening: https://mikedilger.com/gossip-relay-model.mp4
