[[mw:Special:UncategorizedPages]] lists uncategorized pages from content namespaces (not only main but also Extension, Manual etc.) but there's no way to list uncategorized pages from namespaces which are non-content and are not (currently) File, Template or Category. It would be better to have a list of all uncategorized pages, preferably with the option of filtering by namespace with a dropdown as on [[Special:NewPages]] (it's a different but the UI should be consistent). For best implementation, this depends on bug 39659 (to avoid clutter) and bug 12942 (to avoid multiplication of special pages or excessively long lists).
Wouldn't the clutter from Talk: pages make this unusable?
