It seems like we can create a situation whereby if there is a field that is present on both the product and the variation then only the variation field gets used and the product one gets skipped.
For example if you have a field_image on products and variations we get errors after parsing the upload saying that the field is empty using default - and if we continue we see values populated for the variation but not the product.
I wonder if it makes sense to add a unique identify to product and variation column headers?

It seems like we can add a third parameter to formatFieldDefinition that defines whether we are calling with a variation or not then we get all fields for product and variations present although weirdly weight is now included after the variation fields for a product.
