Mediawiki should allow namespace-specific copyright notices, for those wikis that have most of the site licensed in one way, and a particular namespace(s) licensed in another way. It would be possible to accomplish this with {{#ifeq: {{NAMESPACE}}|...}} except that {{NAMESPACE}} doesn't always transclude from Mediawiki:Copyright. (It does in the Mediawiki namespace but not everywhere else)
See also bug 4469 (actually a duplicate, but is about site notices)!
