I discussed this once at Wikitech-L, but somehow never filed a Phab task (or maybe I did file it, but I cannot find it now; please mark this one as a dupe if you can). I recalled this thanks to the somewhat related work that the Research people are doing: T182211: Develop a standalone classifier for section translation (alignment) across languages.
There are many common section headings in Wikimedia projects: Biography, Early life, Filmography, References, Etymology, Understanding (Wikivoyage), and several dozens (or hundreds) of others. They are common in many languages, and a list could be compiled so it would suggest automatic translations. Such translations may be better than machine translation from Apertium or Yandex, because they'll be in the right context, and based on the wiki editors' existing experience.
