Proposed by bennylin at https://www.mediawiki.org/wiki/Talk:Universal_Language_Selector/Design/Interlanguage_links#Language_related_to_the_topic for the purposes of sitelinks prioritisation on the client. I find it unlikely, but I'm duly submitting for consideration.

An article can have a "preferred" badge for example. This can then be used to rank the sitelinks.
At that point it is no longer a Wikibase issue. I am closing it here as from our side there is nothing to do on top of providing badges.
