In the proposal, the user doesn't know anything about the EV indicator.
The browser simply prominently shows the user the highest level of identity information on first POST (maybe with a two week delay on fresh browsers).
Do you trust:
- amazon.com
- Apple, Inc. (United States)
- apple.com-yolo.swag.ru
The proposal is particularly neat as it doesn't discriminate against well known domains with DV, just shows users what the cert proves at the time they most need to know.
I could make this in a day, and prove it improves end user security, if Ryan (or anyone else) would let me.
(I'll address your scenarios in another comment, just wanted to clarify the identify-on-first-POST proposal first)
