So the problem is not solved for developers by leaving these things out of standards, where there is a strong use case.

Still sounds to me like "Made for <insert everyone's favorite 90's browser here>, and best viewed at 800x600" … and look how well that turned out. Even if we don't focus on mobile devices, it seems like a silly requirement as I can just adjust my browser window to whatever size I want (there is no reason to believe I won't be able to do that on future mobile devices). I.e., screen size and application display area are not the same thing and this metadata attribute seems to assume so.
