I think the redirects issue has been raised here to make up for the poor Wikidata-Wikipedia integration we currently have.
I imagine Winter showing a list of "related articles in other languages".
Reusing one of the examples: when viewing [[en:Rob Bourdon]], the software should infer from [[d:Q19205]] that Rob Bourdon is member of Linkin Park (Q261), for which the German Wikipedia has an article, that will in turn be linked. Very little brain work is needed to understand that the German article about the band is likely to contain information about individual members.
While this may sound Reasonator-ish, if correctly implemented in Wikibase it could improve interlanguage and interproject links in a way that just cannot be achieved with redirects. Imagine the Wikipedia entries for "Linkin Park" linking (pun intended) to Wikiquote entries of each member.
