From my experience with the F10/N20 combination, it's my impression that the ZF 8-speed transmission is clutched nearly all the time it's not actually shifting, even when cold. To me the implication is that a light foot is important mostly for the sake of the engine and turbo (high torque demand at low rpm) at low operating temps. Either way, it seems best to drive moderately until everything's warmed up.
