If there's better ways we should certainly consider them. We have to bear 
in mind though that fallback is something most authors don't spend much 
time on, so the ideal is that having good fallback is _easier_ than not 
having fallback. We should definitely not end up in a state where you have 
to do _extra_ work to get fallback. (This is one of the big problems with 
the way the ARIA spec is designed; it assumes that authors are going to 
first spend loads of effort making a widget out of <div>s, and _then_ 
they're going to do even _more_ effort to annotate it with ARIA roles. We 
don't want to end up in that kind of situation.)
