Please, return back categories as they were before the change. As Porter21 says, the usefulness of categories is also to navigate through the category tree. If a category has no content it should be marked as such.

Just because an article does not exist doesn't mean we can make it blue because there are lots of pages linking to it and you can navigate through Special:WhatLinksHere.

Also have in mind that there are wikis that disabled the CategoryGalleries.

There should be an option for wikis to turn that feature off.
