I would like special pages to show my copyright message as wiki pages do. I dont like the "two different" footer looks that you get. Also for example search results with abstracts do still come under the copyright. In addition the copyright is a way to get your own messages easily in the footer (without editing the skin directly). There is no specific footer text functionality (well not that hasn't been recently reverted).
Maybe this could be an option if wikipedia doesn't want it to function like this ?
