I find it strange that the static force of the suspension hanging down would cause problems compared to the dynamic forces of driving over local (our) roads or more extreme situations like railroad crossings or hill crests where the car gets light before coming back down hard on the suspension.
It is real enough for Porsche to release a TSB back in the day about how to check a vehicle for signs of exactly this behavior, suggesting voiding the warranty if the evidence is found.
