You don't need NIP-65 to implement the outbox model.
Discussion
What’s your definition of the outbox model?
Relay hints? Those are horrible.
Clearly we all aren’t in agreement about which definitions mean what.
Is outbox more so the philosophy of:
“reading from the relays others write to”
If so, that makes sense. There are different ways to achieve that beyond NIP-65.
Yes, that's it.
Relay hints can be useful for helping clients create a local database of where to find whom (aside from immediately loading notes you know nothing about), specially when you don't have any other clue about that, but NIP-65, NIP-05, nprofile hints, random guessing and historic event fetching stats, asking some smart indexing services and whatever else could also contribute.
“The [Relay] hints system will never be sufficient, because it encodes changing data into immutable events. The gossip system can be much better (though not perfect), because pubkeys are far more permanent.” ~ nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn
If you change all your relays after being censored (the main value proposition of Nostr) then all your Relay hints break.💔
Relay hints are horrible.🙂↕️
As I said, they're not flawless, but they can definitely help. Coming up with an example in which they break doesn't imply they're horrible and should not be used.
You have just cited a wrong claim from the hodlbod without addressing any of my points. In case you want to do that, here are some more points for you to address: nostr:naddr1qqyrscm9xajxvve5qyghwumn8ghj7enfv96x5ctx9e3k7mgzyqalp33lewf5vdq847t6te0wvnags0gs0mu72kz8938tn24wlfze6qcyqqq823c6zx8e4
Interesting approach, I had not considered using relay hints indirectly to infer where someone might be if you can't find their 10002.
