“sensitive” clutch, why is that?

Again and again I read, and have made the experiences myself that the clutch is extremely “toxic” “sensitive” etc.. Well, I have now become accustomed to it and absolutely no problems with it, but the question is: why is it so extreme, and apparently only with the TDCI? Something the developers must have thought about? A statement that I once heard: This must be because of the high torque, because the clutch otherwise “slip” when switching and thus se Can that be?
