I don't know, I suppose it depends what authors would want. The  
"Automatically reversing transitions" chapter of Transitions seems to  
suggest that symmetry is desired, which seems difficult to achieve  
otherwise.

Right. To me the cases don't really seem all that different, I see it as a  
computed value changing from an animating one to a non-animating one, or  
vice versa.
