Oh, exactly. I also see the need to have a way of privately requesting outside communication lines.

For example, we met on Nostr. We wouldn't be able to privately share external contact info if neither of us had DMs enabled. I can see a case for allowing people you follow to request a temporary DM or external contact method. I approve and it either let's you message me or automatically sends you the external contact info. Just some brain vomit. It's probably more complicated than that. 😂
