I suspect the Karlsruhe schema is a bit like the license change. Everyone thinks they have a better idea, and it will take 3 weeks of back and forth to go over it before they figure out that it's the best (or, least worst) way forward... but by then another 3 people who need convincing pop up.... then 9 then 27... until you reach the tail off of the s-curve.
