That effort has completely different goals and again it's to prettify
the pages, it has no direct value for OSM's data.  But even there the
pair of coordinates is not enough -- how often do you click the
geohack link on a wikipedia page to be taken to a zoom level that's
completely off?

A place on the map can be at the same time a POI, in the middle of a
street and inside 10 different polygons.

(Hint: it's not for rendering).

I don't really care where that link is stored, but Linked Data ([1])
is definitely a good thing and wikipedia currently provides no common
way to add links to osm objects.  Also wikipedia page titles are more
stable than our IDs and when pages get moved redirects are usually
added.  Effectively a wikipedia page's title + language code is a kind
of Universal Resource Identifier.  The other 10000000 data bases can
use the same kind of identifier, or a different one, but let's keep
the information somewhere that two objects in different data bases are
effectively the same real world object.  There are endless
possibilities this brings to our data users.

Obviously things will be out of date at times, like all of our tags.
Nothing new here.

Yep, if you're removing something, especially using a bot, and without
even attempting to contact the authors or the Data Working Group
you're a vandal.
