The user right "editusercssjs" should be split into "editusercss" and "edituserjs". Javascript can be dangerous, esp. on larger wikis where there are a lot of sysops. With the right split, a higher level user (e.g., bureaucrat) could be allowed to edit .js while regular sysops could edit .css. Also, if possible, splitting this right for the MediaWiki namespace as well would probably be a good idea, though abuse there is less likely as it usually has more eyes watching it.
CSS can contain JavaScript, at least for Internet Explorer (see http://feedparser.org/docs/html-sanitization.html). So this separation does not achieve the security you want to have. Of course, splitting the rights might still be a good idea to prevent sysops from accidentally inserting vulnerable JavaScript code.
Fixed in r54153.
