This is going to be called "unified mode", the reason for that is there is no way to indicate the source of an event, like if it is from the aggregator (and may have a low chance of being spam) or a paying user

Would nostr:npub17n4cuc4d6y6qh89dekvxrenfkt5s0n49xns00uavjaxpr36c55dq87fyh9 be open to a "relays" field in sent events for use cases like this (to indicate if it is from the aggregator, inbox, etc.)

This would also be related to the proxy-relays proposal
