It also says device-width shouldn't be used for new code, which is what 
I have a problem with and I will not be able to use CSS4 if it is 
deprecating device-width.

device-width solves problems for me that are not solved by other 
methods, namely the ability to keep the layout the same for the device 
regardless of how many CSS pixels are currently available.

That's a design decision but it is the design decision I use for a reason.

deprecated means it may not be available at all in future version of CSS 
and should be avoided. Deprecated means on the track for removal.

I'm saying it should remain optional, as it is now, but remain available 
and valid - not be deprecated.
