Yeah you can put it in your MediaWiki:Common.css to make it affect the whole wiki. Also yeah a warning would work better than CSS, because not everyone will know that its hidden via CSS, or how to disable it. Wikia could probably add a warning that you're changing groups that you can't undo (which is currently represented by the * next to the group name).
