[webpayments] Is tracking payment request state necessary? (#35)

The paymentRequest API tracks the payment request state:


enum PaymentRequestState {

The Web Payments CG Browser API proposal does not:


Should we report payment request state back to the payee and enable the payee site to react as the payer proceeds through the payment flow? Or should we avoid exposing this level of detail in an effort to reduce the cognitive overhead for the developers (simpler API) and implementation complexity for the API (easier to implement for browser manufacturers)? In short, what are the use cases for reporting the payment request state back to the payee?
