Yeah, because I think they showed that the Byakugan is actually a thing of the Otsutsuki Clan, so I have a reason to believe that the Rinne Sharingan is actually the mutated form of the Byakugan, hence the similar abilities of seeing chakra, and both being a Dojutsu when the Shunju didn't even have eyes. And because only the Otsutsuki Clan had Byakugan, it's only logical to think that other people would manifest other things since they didn't have a Dojutsu to begin with.
