RelatedSites extension is being deprecated. See T185206: RelatedSites: Code stewardship review for more context.
Several of the wikivoyages we will be de-deploying this extension are quite small and lack the resources to remove all the links themselves. Quite a few of them have inactive village pumps and it's very hard to get consensus. I don't imagine any backlash if we just go ahead and do this, since we have announced it and haven't received any feedback.
This task is to create a script that will remove all RelatedSites links all from pages on a given wiki
I will follow this up with separate tasks for removing the extension from each wiki.
