Well, this Beta tool only serves to modify JavaScript, which means the UTC clock for the Wiki if would work, while common pages MediaWiki (without .css and .js in the end of the title) as to help to work the YouTube template, are not available for editing, (thankfully, not all, some have already been unlocked) including to create MediaWiki pages with custom title (as to create other types of templates other than YouTube).

So yes, I would recommend making changes in JavaScript if the Wiki has the Beta tool activated. I also leave an additional link of common MediaWiki pages that can be edited for now. Link.
