Could it be made possible (perhaps as part of the database changes for 1.5?) to
show interwiki-links TO a page? And even more important: Could it be shown for
images on WikiCommons which wikis are using that image?
T68293: Make a special page to expose iwbacklinks
T14833: Provide Special:ExternalLinksFromHere which displays in-line links from Wikipedia, Wikibooks, commons, meta, etc.
