Ok cool, so then yes, for the public events, your plan is a good idea, it's what I would think everyone would want..
and I am simply trying to ask around to see if client devs lives could be made easier by a field in the nip-65 relay list, that clients can show their users "hey, if you wanna message the inbox of this person, here's a link/payment/etc". For some reason they're really stuck on these free access relays for inboxes.. might have to habla.
