Re: [webpayments] PROPOSAL: The PaymentRequest object SHOULD NOT expose internal state information to the developer. Any design that requires developers to manage or understand the request state is a compromise in the API design that should be avoided where possible. (#64)

Agreed with @adrianba here. State isn't required, either from an implementation perspective or from a web developer perspective. But it is very useful from an implementation perspective (try writing a polyfill without it). But like Adrian, I am not married to the idea.
