Let's say, one UA does support aspect-ratio, but does not re-evaluate  
MQ's in response to aspect-ratio changes. In such a case, I may want  
to help myself, with code, similar to the one shown below. How do you  
expect this to play out on another agent, that actually _does_ re- 
evaluate (and possible re-layout) in response to aspect-ratio changes?

This may well result in double rendering and flashing etc, no? It  
could be helpful, if script code had a way to find out, if "automatic- 
aspect-ratio-re-layout" was actually supported by the agent.
