I think there's a difference between the fabrication drawing that the board house needs for production (which is what DJ is going for, I think) and an assembly drawing that you would use to stuff the board.
Assembly drawings are also used to document the board. Which is usefull for debugging and repairing boards. calibrating boards etc.
I understand the value of an assembly drawing. I was just pointing out that it probably should be separate from a fabrication drawing (which is what DJ originally announced).
If you do all of your assembly in your own laboratory, it might make sense to combine the two. But a board manufacturer doesn't need to know the values of the components that will be stuffed, and when you're stuffing components, you probably don't care about drill sizes.
