How does having opt-in for personal Javascript help security? People are already restricted from editing userscripts for other users, so they can only edit their own. On top of that, the default content is blank, so there's no executable stuff unless you add it. All the opt-in feature does is add an on-off switch to something that already was disabled by default and could be easily turned on and off.

Don't get me wrong, I'm glad Wikia is at least making token efforts in security, and as one of the most paranoid nutjobs on Wikia, I consider security a priority. I just fail to see how this will improve user safety. It's just an on-off switch for something that already had an on-off switch.
