There are several issues regarding Wikipedias and OSM maps:
- WIWOSM is not working in any Wikipedia, as far as I can see (in cawiki, frwiki and eswiki, the links just produce a blank rectangle insteat of a map).
- Before it stopped working, WIWOSM maps were very out of date (maybe several months).
- Links to OSM maps from categories ([https://tools.wmflabs.org/osm4wiki/cgi-bin/wiki/wiki-osm.pl?project=ca&article=Categoria%3AEstadis_del_Jap%25C3%25B3 example]) stopped working.
I'm not sure about how many of these issues are related to MediaWiki or in Phabricator scope, but I expect at least the first one to be.
