See this forum thread, which was created just today. People expect the page to exist if the link is blue. The blue links will tend to lead new users to not create categories at all - as they think they already exist. If putting a page in the category makes it exist, is there any need to put text on it? Not in the eyes of the average editor. Categories may not be strictly intuitive, but they do organize information better for search engines. I think the moral of the story here is if you're going to change default functionality, you should add a preferences option to keep the default.
