If an RP expresses their expression of trust in FxA issued assertions, 
would the verifier only accept FxA issued assertions, or would they 
accept assertions from both FxA and Persona? If the latter, is a user at 
greater risk of having their account on the RP controlled since there 
are two possible paths a bad actor can use to sign in?
