I feel like the whole reason this exists because we don't have routing or gossip on all clients, so people are trying to find work arounds to make Nostr more usable. If we had routing and gossip, we wouldn't need this most likely. 

 Well, this breaks gossip in clients that have it. It would be possible for a proxy to add gossip to clients that don't, and that would be awesome, but this isn't it.
