Re: [webpayments] Registration: Should we support payee knowing user has payee-controlled payment app? (#112)

@burdges people do this now and don't seem too bothered by it.  It is how all of these payment apps work.  In a push payment world, the user agent would just be a conduit that relayed information, but I would still want my payment app (e.g., paypal) to have the final say about shipping address, source of funds, etc.  Then paypal (as a push payer in the future) would send a token to the merchant / merchant's payment processor to send the funds, and complete the Promise in the browser environment saying "payment complete" with a transaction token.
