It would be helpful to have a magic word NOCATEGORY removing all categories from a page. The content of pages like sandboxes or certain maintenance pages changes frequently and add unwanted categories from transcluded templates. There is no other possibility to fix this issue efficiently apart from removing or hiding somehow all categories on the page, see the discussion at http://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical)#__NOCATEGORY__ .
