Still present in zc157, but applicable to prior versions as well.
If a category has been removed, any category-listing page-links that were previously slurped by a search engine can't be removed since the Zen Cart response to an invalid category results in the page being met with a <meta name="robots" content="noindex, nofollow" /> link instead of an HTTP-301 (moved permanently).
You can see this behavior with a demo-products' install by attempting to access the site's /index.php?main_page=index&cPath=99999. I'm just wrestling with what the 301-redirect should (er) redirect to ... new_products (some sites don't use this page), all_products (ditto) or the home page.
