Call for +1 on shipping address and contact info delegation- Chrome's intent to ship

Dear Web Payments Working Group,


There were some feedback on Chrome's shipping and contact delegation demos
[1] during TPAC-2019, now we are blocked on explicit developers/browser
vendors support to proceed with shipping the feature.

Please +1 here or on Blink's intent-to-ship[2] thread if you think the
feature is useful. For further details about explainer, design doc, spec
changes, web platform tests, etc please check the intent-to-ship thread.


* Feature Summary:

Change the Payment Handler API to let the browser delegate handling of
shipping address and payer's contact information to Payment Handlers.
