Why some Product Permalinks contain SKU?

Permalink is short for “permanent link.” Permalinks are permanent URL structures used to help organize the content of your website (pages, posts, products, etc.), so it can be efficiently navigated, shared, and referenced by users and bots. WordPress requires something unique so it can distinguish categories from products.

Therefore during WooCommerce import, product name duplication, LitExtension will customize product SKU to permalink to avoid possible error.
