These were inconsistently applied, and weren't used on all nav items. I.e. the navigationsite navigation items had them, but not the login/signup links.
They're only intended for things that behave like menubars/dropdown menus (I.e. are navigable by up/down arrows, as commonly found in applications.)
As a screen reader user myself, this ARIA markup actually made the navbars less accessible, so I've removed them in my own site. But I'd suggest that this be merged, as it is an incorrect use of these roles.
