His solution is simple and obvious, while a category name need not be specifically designed for namespaces, all it is a text label. Currently, the category label is going to be displayed with both parts, but I imagine that the maintainers of the wiki code could be later convinced (after busting behinds to get UCP up and running) to add an obscure option called "Hide namespace in category name", where a category button would be displayed without the prefix if on a page where the prefix matches the namespace of the article. It could probably be done in less than 5 lines of code.
