I understand that, but the proposed text is trying to define certain
states that are distinguishable to give different advise, and I tried
to show that one cannot distinguish some of those states. You cannot tell
implementarors that "indeterminate" is different from "bogus", and
that a browser can give different feedback depending on those two
states. Not from a security context anyways.

I'll try come up with an alternative text.
