Ah, I see. I was implicitly assuming that the parent's other requirement:
> different pseudonyms available that __don't reveal your 'true' ID or other pseudonyms to the site owner__
(which isn't offered by Facebook—right?—and which does require trust in the issuer) would be part of the putative Google Identity.
On the other hand, having spent this much time arguing that it wouldn't happen, I'm now wondering why OpenID with Google as 'vouching agent' (or whatever that part is called) doesn't count.
