What happens when my on-premise subscription license expires for workflow and forms on PRODuction?

I read this article.

I think this is outdated or wrong information in the article.

I have expired subscriptoin license on DEV env and I can't create/modify workflows and forms.

Also existing workflows are not firing now.

Will I have the same behaviour on the PROD env?

I can't find related information on Nintex resources.
