On the other hand for the "landmark" roles which specify semantics but not behavior, I would agree that sticking with HTML elements is a better approach. Even if there is associated behavior for them, such as a hotkey, they will degrade well to older user agents.
OK, but we still need to specify what happens when they are used. To take the aria-role="heading" example again, I believe it's a requirement that a page that uses that has the same outline structure when viewed using a tool that uses an accessibility API as it does when viewed through a tool that accesses the DOM directly.
