How important is it for a complete kitchen to have a Dutch oven?

I already have a slow cooker and an Instant Pot. I have a bread machine and a stand mixer. I have a couple of cast iron fry pans. I have a complete set of pots. But I don't have a Dutch Oven. When I subscribe to "Cooks Illustrated" and America Test Kitchen, I see a lot of recipes for Dutch Ovens.
