"Enthusiasts" remove the shafts all together because they aren't necessary and its just one more system that can cause timing belt issues.

Not quite the same thing.
What you are referring to is removal of the
balance shaft, not an
intermediate shaft. The makes you point out use a rotating mass to dampen vibrations. The IMS in a M96 Porsche is not there for this purpose, the crank turns one end of the IMS, the other end turns the camshafts; remove it and the engine will not operate..................
