On the English Wikipedia the page title formatting level is never used in article space, although I understand it is used on some other wikis. It might be that other wikis do not use a dfferent page style.

Accordingly it would be nice to be able to remove/suppress/disable this item from the list on a per namespace (or, less ideally, per wiki) to avoid confusion to new editors.

Unless this is absolutely trivial to implement, please regard it as a low priority enhancement request.
