Right, and when people who haven't paid that much attention to the machinations of the WebPKI (who could blame them) talk about how weird it is that the browsers killed EV, this is an important part of the backstory: EV was mostly a failed attempt to make the WebPKI do this kind of "do-what-I-mean" entity authentication.

The problem as I see it is: there simply isn't one coherent global notion of what entity authentication means. It's situational.
