That depends on where you draw the line for the UA box. If you split the  
browser into multiple processes, are they allowed to send different  
representation of the data between each other? What if you move some  
processes to different hosts?

It also depends on what your view is on the authority over data. Should  
the origin server overrule the user agents decision? If the user agent  
explicitly asked for compressed data, should the origin server be allowed  
to overrule that? Should no-transform defeat all network security  
appliances?

In the case of current Turbo it's not HTTP so the protocol requirement  
doesn't apply.
