User blog comment:MisterWoodhouse/Fandom is upgrading to a modern version of MediaWiki/@comment-38778395-20190621012003/@comment-4632631-20190622015528

The reason they aren't supported by Fandom atm is because they aren't included in MediaWiki 1.19, the software that powers this site rn. Wikis that are on newer versions of MediaWiki support these languages, so that's why there's wikis like the Anglo-Saxon Wikipedia.

So I think updating MediaWiki would mean having more languages to choose from in Special:CreateNewWiki
