  There was a link to disambiguation page which was detected using
other tool which is not using wikidata. That other tool gives more
than 2500(!) items to fix in osm/wikipedia (Lithuania only). So there
is enough work to be done until this particular problem is fixed. It
could take two weeks, it could also take two years.

  It's not only names, but codes and some other details. Wikipedia
page content is probably mixed or swaped (haven't done analysis yet).
  And people were asked NOT to do automatic changes without local knowledge.

  It would not have been a problem if Yuri would not have created a
tool which attracts people and fools them into believing such things
could be fixed automatically.

  I can give another real world example where wikidata usage WOULD be a problem:

  Say we have a church named "St. Brewers church". It has an object in
OSM with corresponding name tag, a link to wikipedia page "St. Brewers
church" and wikidata ref 12345.

  Now this church is upgraded to basilica: it's name (in the real
world) changes to "St. Brewers basilica".

  OSMers do not notice this change (name tag is not changed),
wikipedians do (wikipedia page title is renamed, leaving old 'church'
page as a redirect only).

  If we use QA tool based on wikipedia link, it finds that "St.
Brewers church" does not exist anymore (redirect pages do not get into
geotagged dumps). As soon as I try going to that page I'm redirected
to "...basilica" page. Now I know that a name has changed and I change
it in name and name:xx tags in OSM.

  If we use QA tool based on wikidata, it will find NOTHING wrong
here. wikidata 12345 will be pointing to "St. Brewers basilica" page.
Nothing wrong. No noticing of a change of name. Which leaves OSM with
outdated name and no way to notice (names in wikipedia and OSM do not
always match, comparing wikidata and OSM name is not always possible,
we need to find the fact of CHANGE of wikipedia article name).
