Then yes, I can get behind the idea of that such a communication method would be very useful.

What I want is the ability to have the server ask for whatever info it needs about the client device/environment, and have that sent as a header. And only sent if the server has asked. I don't mean we want "screen size" alone, that is but one example of something the server might care about. Bandwidth is another, as is viewport size, and I am sure there are a lot more. I want to see a *communication method* defined here, not a one-issue semi-solution to an overly specific example of what is in reality a much broader problem (the server not having reliable information about the client).
