I do. We can just drop it. I don't really see a use case for it. The UA  
stylesheet could just use a px length instead. For instance:

   @viewport { width: 980px }

Not really. 'device-width' and 'device-height' are intended to be the same  
as in Media Queries. That is also the case for 'device-width' and  
'device-height' in the viewport meta properties in Safari (not testable  
for device-width, but setting content="height=device-height" gives 480px  
height and content="initial-scale=1" gives 356px (depends on you UI  
config, really) which is 'window-height'/'view-height').

The way to set the width/height to the window height with @viewport would  
be:

   @viewport { width: 100%; }
