If the OP passes a verified email address via sreg or A/X then the RP can store this information and use it for AR purposes in cases where the user has forgotten the identifier used to log into the RP. One caveat is that the email being passed by the OP should be a verified email address. As part of the sreg testing currently underway at Yahoo! we pass the Yahoo! email address attached to the identifier which requires no additional email verification step on the RP's part.
