Once activated, this plugin will override all product status changes and set them to DRAFT. This way you could have a bulk importer and only publish your products once you have already revised and updated them.
To override this status change, simply add a custom_meta to the product with name ‘dropwp_disableproducts_skip’ and value ‘1’.
