fwiw Back when I was working on putting SN on nostr via Outer Space, I was told the caching relays approach to algorithms is the way nostr is expected to work: https://github.com/nostr-protocol/nips/issues/522

In general, I got a strong ossification vibe from the nostr github devs and decided it was too early for me to put energy into fighting them and would let them work it out while I worked on the "garden" part of SN.
