Private Messages on Nostr were a mistake.

I know at least 2 people who sent messages that never arrived. This is an unreliable inefficient API design that confuses everybody and is barely useful, not a great look for Nostr.

Clients don't know how to use them. There's like some Nips that do the same thing but every client does something random. It's effectively a useless NIP.

I'm in favor for abandoning the DM spec as is and completely and replace it with something new.
I think it should include bots for some reason, Whatsapp, signal, pidgeos and facebook messenger. Morse code could be an option too. The sender receiver design with some encryption is too generic and totally inefficent. I want to keep the term "DM" more generic so people can vibe code something around it.
