I must admit I strongly agree with you, here. A combinaison of ARIA (role, 
...) and existing CSS (appearence in particular) seems to be sufficient to 
describe nearly every possible situation defined in the current draft, and 
much more. After that, it's an OS task to understand those informations and 
apply the appropriate touch feedback (if needed), and not a browser task (at 
least, at my eyes).

But I didn't see any advance on the appearance property for a while, which 
can be a concern. Where are we in the standardisation process of that 
property ?
