Combined Listings via the Storefront API

[matt-at-tapcart]

We have multiple merchants with mobile apps who use the Combined Listings app. All of the product/collection data in our apps comes from the Storefront API. Therefore, we're currently looking into whether or not it's possible to retrieve Combined Listing data using the Storefront API.

I see this developer blog post from October 1, 2024 saying that Combined Listings is supported with the Storefront API, but it's quite vague:
https://shopify.dev/changelog/storefront-api-support-for-combined-listings

There seems to be a CombinedListing object exposed by the Admin GraphQL API:
https://shopify.dev/docs/api/admin-graphql/latest/objects/CombinedListing

However I'm not finding anything of the sort in the Storefront API documentation:
https://shopify.dev/docs/api/storefront/latest/objects/Product

I'm also not seeing any mention of Combined Listings in the Storefronts documentation:
https://shopify.dev/docs/storefronts/headless/building-with-the-storefront-api/products-collections

Please advise us:
1. Whether or not it's possible to retrieve Combined Listings information from the Storefront API.
2. If #1 is true, how to retrieve Combined Listings information from the Storefront API.

Thank you in advance!
