Request for Checkout Step information when working with Shopify functions

[vixnguyen]

Hi Shopify team,

I would like to request for adding Checkout Step information as an Input when working with Shopify functions.

Currently we have buyerJourney for Cart and Checkout Validation API, and I would appreciate if Shopify can offer Checkout Step (information, payment ....) to other Functions APIs such as Payment Customization, Delivery Customization.

My use case is:

- As step one, we want to show Amazon Pay

- As step three, we want to hide it

Please let use know if this request is ok or not. Thank you!
