I think triggering when the "effect" property changes is not as clean  
and convenient as triggering implicitly when the value of an animated  
property changes, as transitions do currently.

Furthermore, it seems that this carries the implication that two  
states with identical entry and exit effects will result in no  
animation whatsoever, even if the values of the animated properties  
are wildly different. That seems like a very unfortunate quirk.
