I actually think we shouldn't migrate to NIP-104, I think nostr:npub1zuuajd7u3sx8xu92yav9jwxpr839cs0kc3q6t56vd5u9q033xmhsk6c2uc would agree -- MLS is too complex to become the shelling point all apps that want DMs should support; apps shouldn't need to rely on an SDK to support a feature and building MLS from scratch is hard -- I think NIP-104 should remain a very specific feature separate from generally-available DMs -- kinda like Telegram vs Telegram "Secret Chat" or Telegram vs Signal.
I just think we should completely remove NIP-04 DMs from all clients and NIP-17 DMs should not be sendable if the user hasn't configured inbox relays.
