Currently, Shopware allows properties to be deleted even if they are still assigned to products, which can cause data inconsistencies. To prevent accidental deletions, a warning message should appear when a user attempts to delete a property that is still in use. The message could state: "This property is assigned to X products. Deleting it may affect product configurations. Do you want to proceed?" This would ensure users are aware of dependencies before making changes, improving data integrity and user experience.
