miau. OSM does not have "area" object, thus it needs something to mark object as polygon.
There are some tags that insist that a line/relation is filled inside. These are area=yes and type=multipolygon. All the other tags may mean either line or a polygon depending on context. Sometimes context isn't clear. (Is a circular highway a roundabout or a filled square?..) It is rather distinct that highway=*, railway=* are linear usually, and that landuse=*, amenity=*, shop=*, natural=*, area:highway=* are polygonal. However, there are some cases when it's not true, like the platform. We either need a complete machine-readable list of tags that are polygons or lines, or need to tag each object separately. For now I see just the second approach being used; telling that is't invalid without providing any reasonable fallback is a bad idea.
