And of course point in time recovery does not matter. That can be cases like UAT, STAGE or any non production environments. Fro more info about recovery models read this article.
TIP: Not very difficult to rewrite for switching into any recovery model
WARNING: Executing this script will alter all you databases. If you execute by mistake then you need to take care of proper backup chains when there is need to switch back to full recovery model
