> The connection is secure. TLS doesn't defend against compromised devices.

I disagree. While the *network* connection itself may inhibit the rather technical notions of confidentiality and integrity, this is not what the average user would consider a "secure connection". Staying with a browser example, an unsuspecting user expects to communicate privately with a website.

Yes, TLS alone cannot ensure this, but we are discussing a format which has the potential to scale attacks on users in a much easier way, and making awareness of users a requirement might be a near trivial countermeasure against that simplification.
