Because I am less sure than you evidently are that 5 years after manufacture the general quality and integrity of a harness has so significantly (and suddenly) deteriorated that it is no longer safe -- and, ironically, that it is impliedly less safe than a car's original 3 point lap and shoulder belt, which (regardless of how ancient) as far as I am aware would continue to satisfy DE technical requirements. (I'm not saying that there might not be other reasons to replace 5 year old harnesses, e.g., if they were involved in any sort of material impact, or if there have been significant safety standard advances in harnesses since the old ones were manufactured.)
