Sorry, this is simply not true. The prop shaft threads need to be shortened only if they extend too far beyond the Max Prop nut which is not the case in the majority of installations. Model or age is irrelevant.
Here is a quote from the Classic model installation
instructions (italics & bold type mine):
One thread can be exposed aft of (the) nut system, if more than that are showing it will be necessary to cut off the excess with a hack saw.
