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.
