just brainstorming here, like say i want to set just one inbox, to a relay i trust like nostr.wine. In the gossip settings it says for "inbox" that relays shouldn't require payment. The reason for this I think is simply that it's confusing for gossip clients, they don't know your inbox is paid. Maybe gossip can have an ["r", "wss://nostr.wine", "inbox-paid"] field or something like this? What is the downside of making paid a first class citizen? Would it not be easier to do that sooner, than having clients do multiple queries fired off to nip11 endpoint or nah?
