Looking through the source I'm honestly kind of disappointed you didn't loop me in on this. I spent about 3 weeks implementing my version back in August, and this implementation just isn't going to work for my use case (nostr-in-nostr). Unless I'm misunderstanding how it works, this is just a different way of doing feature-poor group chats. You're right that wrapping is maybe problematic, but the solution isn't to create a bespoke protocol specifically for groups, this is the thing fiatjaf is always talking about.
