I believe this to be a mistake in the structure design, as SKU is required throughout Magento.

This is a database issue, unless you can directly insert the product in the database (or use custom code to import it) without an SKU this is not 'testable' on an Magento github generated development instance.

Reproducible on the latest 2.4-develop
Product is added without issues, even if SKU value is 'NULL'
