There's a practice to add such a node to the boundary's relationwith the role admin_centre (and other *_centre's I guess), which is easier for a tool to understand than a bunch of building polygons. However, the claim that having both a relation and a place= node is duplicate information is incorrect, it's just a different way to express the admin_centre role.
