Relatr also supports nip85. So, you should be all set from the platform side.
But I don't think Clients should force their algo into users. The users themselves should have freedom of choice. Otherwise, we are just rebuilding centralized systems using a much worse architecture.
On the scaling. This is just the beginning. NIP 85 will rank every single event, not just pubkeys, once for each new user, if that user has the event in their graph. We are about to enter a new age of personalization.
