For this to make sense, you have to assume that CSS authors typically read  
the spec before using a feature. In practice, that almost never happens.  
It is much more useful to have something that most CSS authors understand  
well enough to be able to use it as intended without having to read the  
spec or other documentation.

If we have "reset" and "unset", I imagine people will confuse the two and  
will have to look up every time which one to use. I consider that to be a  
language design failure. It's like replaceChild(nodeA, nodeB) in DOM -- it  
is ambiguous and impossible to remember what the argument order should be,  
so I have to look it up or trial-and-error every time.
