Network property is in Germany set to road even a network is available. The streets should always have a network so that the streets can be equipped with the national signs, as with mapbox street style.

Projects like openstreetmap-americana use the route_n tags instead to render highway shields since a road may belong to multiple networks. They publish the highway shield renderer as an npm package too.

From my point of view, it would make sense to include this as a shield property in transportation_name.
