I think he will have it. And we don't know yet how powerful CoC can be.
After all we didn't know that Coo could allow to see seconds into the future when pushed to its extreme and that CoA could damage the interior of an object or of a body without even the need of a contact.
It's Oda's way of writing, for now CoC is mainly for fodders but you can expect it to have a greater impact later in the serie.
