We've addressed most design concerns like this (which are generally 
legitimate concerns) in the ARIA FAQ.

The goal was to have apps that still work normally in legacy browsers. 
This means all the code to implement widgets needs to be in the JS of 
the page.

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.
