Tldr; soon 😅

I think it's because searching in nostr is very hard right now. You can't query a relay and tell it to return a profile with a nip05, to do that you'd have to have a database of enough pubkeys to find them that way. So, as you mentioned you could consider sharing links that go to a site you know will work with a direct link. That way newbies can start with that client and/or oldsters know what you mean. Otherwise ya, without a link, very hard to find someone by their nip05 with a fresh client. Someone correct me if I'm wrong here..
