Re: [w3c/payment-request] Spec is silent on its role in facilitating arbitrary communication between top level contexts (#936)

It seems like we should pointing at [this solution](https://github.com/w3c/payment-handler/issues/351#issuecomment-566642121) which I hope has been documented somewhere in the Payment Handler API.  

Maybe I'm missing a level of abstraction - do we expect the payment request API to point at anything other than **THE** payment handler PI?  If not, then why not point to the concrete fix?
