I&#x27;m all for rolling out opportunistic STARTTLS, but I don&#x27;t see how you can surface it in the UI in a way that&#x27;s meaningful to the vast majority of users.  If STARTTLS was not used, the message might have been intercepted. If STARTTLS was used, it&#x27;s less likely it was intercepted, but it still easily could have been.  (How much less likely? No one knows for sure.)  How is this information helpful to users?<p>Let&#x27;s get things like DANE and pinning deployed first.  Once Gmail can make a strong assertion that a message was securely delivered, then it can surface this information.
