To make T128326 easier, we can go ahead and remove support for Citizendium. This will simplify any migration efforts. Citizendium is English-only, and currently no English Wikivoyage articles link to it:
https://en.wikivoyage.org/w/index.php?search=insource%3A%2F%5C%5B%5C%5Bcitizendium%2Fi&title=Special:Search&profile=default&fulltext=1&searchToken=b8oechbg6vw9j7x4r8crok59d
Just to be safe, I also checked all of the top-10 Wikivoyage projects, and none of them have Citizendium links.
