It only returns keys for content namespaces, even if called on a title in a talk namespace. This causes code duplication everywhere where the distinction is necessary, as well as interop issues – e.g. SkinTemplate has it's own way of converting these keys to talk keys, and it has to be faithfully replicated in skins that need to even slightly mangle the navigation links. (Or maybe a different function should be introduced, to keep backwards compatibility? It appears to be used in a few extensions and extension-skins, including LiquidThread; I didn't check if these actually depend on current behavior.)
