Your arguments could apply to most CSS shorthands. Do you disagree with them as well?
For example, background could easily have a "50% black" sequence.
In practice, authors find CSS shorthands that require a certain order (e.g. font) hard to remember, and avoid using them for that reason. Please note that Iím not speculating here, authors tell me that all the time.
People have their own coding styles, and should be free to. I agree that positions after colors are easier to read, but I wouldn't go as far as to spec my coding style and force everyone to follow it.
