Perhaps I don't understand your question. It's Microsoft's call as to  
how to standardize their controls like a WPF grid. I thought the point  
of WPF was that the control could look like anything, but the  
programming framework would understand its semantics. If that's the  
case, then the framework should hand those semantics off to MSAA. If a  
grid isn't accessible in a desktop app, how would its equivalent be  
made accessible on the web?

I'd disagree with you here. I am very thankful that VoiceOver's  
interaction model was not designed by a standards body.
