Hey there, I know that the extended minifigure legs are already in the LDraw Parts Library, but not the extended minifigure arms.
87773 - Arm, Left Long
87774 - Arm, Right Long
Even though LEGO no longer produces these extended minifigure limbs anymore, I still believe these parts will come in handy for designing new minifigure concepts (Professor Utonium from The Powerpuff Girls for example), and I would really love to see them added to the LDraw Parts Library someday.
