I'm NOT convinced by Onoki's arguments. He's worrying about youngsters becoming weaker and thus vulnerable to danger but what he proposes will let the akutas take all the real fight experience and make the shinobis even weaker...

So apparently Akatsuchi sees Kuu for the first time (with the surprised face when he sees Jinto) so Ku must not be Onoki's real son but some new clone of some sort.
