No, those are very different situations.

Layout is under author's control and is known to the author when the page  
is authored. UA characteristics are not, and different UAs will have  
different requirements.

Conversely from UA perspective: layouts vary wildly between pages, so UA  
can't really mess with them. Bandwidth/DPI requirements are known to UA  
and there can be same set of UA-specific rules that works for all pages.
