My point was that Qt was late in entering the game with the addition of an 
alpha channel to the color object.
We have an alpha there now, and its certainly not an exception to the 
rule. So this is not a "if you come from [whatever].." this is more an
"embrace change and use the new concepts to the fullest".

I expect people to adjust to the new concepts over the duration of the 
KDE4 lifetime and when they do, then it becomes weird when there are two 
conflicting ways to set the blending amount.

Its all a matter of perspective and I doubt its wise to decide right now.
