Not sure if WHATWG is doing anything, but in the W3C there is  
https://dvcs.w3.org/hg/screen-orientation/raw-file/tip/Overview.html in  
the Web Apps group (by Mounir, who works on Firefox OS as a day job)

I expect to know a bit more about the implementation status of this in  
about a week, when the group has a face to face meeting.

cheers
