This seems very complicated. As a left curve individual I want to query a service and get the stuff I want, very fast, and yes that includes personalized Pagerank.
It's up to the service to cache internally if it can't do realtime, no need to generate a massive amount of events.
As a client, I can ofc keep these signed results cached if I want, put them on a relay, whatever. I just don't think this belongs to a spec
