Wikidata is broken.
It has allsorts of kludges to link items to the items they should be in.
Lets merge all these Categories, lists, duplicate articles in a different
language etc. with the items they should have been part of from the
beginning. (Normal rules apply - If you were to describe the Subject of
each using properties could they be the same properties)
We now have the tool to fix the wikibase client problem - Badges!
If duplicates have suitable badges then wikibase client can use these to
keep the language links. wikibase client will also be able to add other
lists
"articles on the wiki in other languages" for instance
