It would be nice to display multi-level OSM relations on wikipedia / wikivoyage. For example this hiking path: https://www.openstreetmap.org/relation/2110963 - note that this is a relation of relations, not a relation of ways. The wikidata element is here: https://www.wikidata.org/wiki/Q95735225. As far as I can see, the mapshapes template support only relations that have ways as members.
