A more far-reaching and better solution has already been discussed for
years, namely porting the interwikis to a separate (wiki) site, so
that such changes can be made at once for all languages rather than
having to be done separately at each. Maybe that will be worked on
with the data project the Germans are setting up.
You mean the Interlanguage extension, right? The extension page says it is
stable, so maybe the projects just need to start actually using it?
