In regards to Dev Wiki - we want to make sure script updates on Dev Wiki go through the JS review process. The simplest method of doing so is to migrate them to the MediaWiki namespace.

This is very much a work-in-progress, and we want to do it in a way that allows Dev Wiki to continue to be used for creating and improving useful sitewide scripts, while not causing everyone to have to suddenly rewrite their imports.
