...'cept, Hagoromo is. Except, we don't know that. What we do know is that the clans are distantly related. We don't know from what point in their bloodlines. And we can assume that Hamura, in addition to the Byakugan, has the "Sage's body" so to speak.

No, we absolutely know that. There is absolutely, 100%, ZERO room for debate there.
