Russian Wikipedia just replaced all of their map links in the upper right corner (geohack) with the <maplink> - Kartographer extension! Moreover, when clicking the link, it also shows the location outline, if that object exists in OpenStreetMap, using corresponding Wikidata ID. My deepest respect to my former Interactive Team colleagues and volunteers who have made it possible! (This was community wishlist #21)
Example - city of Salzburg (click coordinates in the upper right corner, or in the infobox): https://ru.wikipedia.org/wiki/%D0%97%D0%B0%D0%BB%D1%8C%D1%86%D0%B1%D1%83%D1%...
