Is it terrible or is it advanced and you weren't there from the ground floor? Can you see a way to deliver the same features without becoming as complex? Or is Nostr going to stay forever as simple as it is now to keep the simplicity claim?

There is a good chance Nostr will stay resistant to features (Nip26 not widely adopted nor any alternative), but then the question is how are we going to have personal data stores, more user friendly identity and private chats and VoIP?

My answer is as I said, an identity that abstracts Nostr and email and others, so clients that want these advance features can actually compose them.

The good news is, that is already possible without the permission of any protocol or client. But it will expose interoperability for what it is; very political.
