Why doesn't the Rates API permit quotes with country and postcode?

Hi forum,

I've been looking into integrating EasyShip with our PayPal flow using the PayPal's shipping module

https://developer.paypal.com/docs/checkout/standard/customize/shipping-module/#overview

(Un)fortunately the callbacks from PayPal redact the address lines, and the API docs seem to suggest that even the postcode, city, or state could be missing:

https://developer.paypal.com/docs/api/orders/v2/#server_callback

It looks like now I'm going to have to change my flow to get the address up front on our website, which could impact sales.

Is getting shipping rates without the address line a possibility either now or in the future?

Thanks
