Opera has already been forced to do this.  For example, in its 
projection mode it matches both the "projection" and "screen" media 
queries (technically a spec violation) because of all the sites that 
explicitly say "screen" when they really mean "not print" (or in the 
absence of that query in downrev UAs when they mean "screen, projection, 
tv").  Now of course part of the problem here is that "screen", 
"projection", and "tv" are mutually exclusive, which is in retrospect silly.

This is an excellent example of the fundamental divide about optimism vs 
pessimism here: the things that web authors doubt UA vendors will be 
forced to do because of web authors making bogus assumptions are things 
that UA vendors have already been forced to do for years because web 
authors ... make bogus assumptions.
