Perhaps this idea could be extended to treating content differently for all messages from unverified identities. Getting people to verify identities in an end to end encryption system is a huge problem. This could provide a conceptual hook that would mean that unverified contacts were untrustworthy contacts. This would be a state, rather than something that you get nagged about from time to time. Otherwise an attacker will usually be able to figure out a way to fake a message from someone already in your contact list. Of course iMessage doesn't do identity verification which is why it does not have effective end to end encryption in the first place. So they would have to solve that, perhaps larger problem, first.
