Sort of. The main difference would be that no-mixed-content would 
inherit into framed content. Specifying 'https:' can ensure an insecure 
framed document wouldn't get loaded but it cannot prevent the frame from 
itself including http: content.

Alternatives might be to specify this instead as part of the <iframe 
sandbox> attribute.

We might also decide that it's dangerous to allow a possibly malicious 
parent document to block selected content in child frames, although that 
ship has already sailed somewhat with <iframe sandbox> in the first place.
