yeah they are truly insane
i will be implementing it how i think it should be, especially if i do get a grant to do so... it's on my list of things to do but it's currently behind nip-79 nostr relay chat because i think that is probably more important (this means relays bouncing ephemeral messages carrying instant messages, including ones to other users using nip-44 encryption, but the relay doesn't store them, so clients have to do something else for that, i haven't thought about how to do it but first priority is live messaging
i'm totally ripping off the interface design of telegram for it as well, since i think that nostr devs like telegram, and it is a very neat, minimalistic design
