I don't think, I know that the jerk has been engineered. I know for a fact that DSG does exactly what is say it does and more. The 0.2s improvement is the minimum and remember it's only a 6 speed box and not a 7 speed like the DCT.

Then you increase tension on the next gear and reduce it on the previous gear clutch. both clutchs are slipping but the car is still accelerating.

Eventually the next gear clutch if fully engaged and the previously one disengaged. Basically you are slipping the clutches to dissipate the energy. Lots of wear and tear on the clutchs but smooth aceleration. From what I have read this is how the veryon does it. Not something I would want in a car that gets driven a lot. You are also wasting the stored energy in the flywheel and turning it into heat in the clutchs instead of acceleration.
With the Veyron you are not talking about a piddly 400hp, the Veyron has close on 3 times that amount. If you reckon that the clutches will be damaged then I think you are misunderstand the technology.

I won't disagree that awd does put extra strain on clutches, especially on standing starts. But I know SMG has given more problems because of their S6 mode than anything else, I ask you how many launch control starts will an M5/6 be able it perform after another.
