REST API endpoint for "virtual" SKU entity level

Who would benefit?

Any customer with three (or more) levels of product data, where the lowest level is stored in a JSON/XML field in the lowest entity type (usually Item level)

What impact would it make?

Reduced complexity when fetching data, as there is no need for post processing of the JSON/XML data. Instead, the data could be fetched as SKU entity level data

How should it work?

My proposed solution is based on a VERY common approach where the data model has a field for SKU level data. When using REST API to fetch data, the fetch must be configured in such a way that the field must be treated as an array of entities, and the data returned as if the data was actually coming from linked child entities (with data in separate fields).

Why is it needed?

Reducing complexity when data is exported
