If you are interested in exploring it..

This PR seems clean enough, but adds a little complexity with multiple relays and multiple keys per conversation pair. It works even for group chats, since users can have access to separate aliases even inside the same group.

I guess cryptographic forward & backward secrecy would be the most important addition, along with hiding the recipient metadata. I see Jeff started double ratchet at https://github.com/nostr-protocol/nips/pull/1206 and moved on to MLS. I'll take a look.

I think forward and backward secrecy are unachievable in Nostr. You can either be able to load your DMs in many clients and not have any type of real forward and backward secrecy OR you can have DMs that are only visible in the originating client, and thus "broken UXs" everywhere else and then yes with forward and backward secrecy.

There is no way to do both.
