[OpenID] [oauth] Re: Replacing email verification with RSS 'push' feeds and OAuth

Currently, Google OpenID users can be exempted from Email verification 
when the Google OP returns an @gmail.com address, because the Google OP 
will only return the @gmail.com address that is tied to the Google Account.

If we generalize this, if the RP trusts the user's email provider to 
always assert the user's true email address, then why wouldn't an RP 
trust the OP to always return a valid disposable email address?
