I have brought that up many times but it was shaken off because people don't like the notion and come up with different meaning for what was stated. So that may be the reason, giving birth to Hagoromo and Hamura cost her her Rinnegan and Tenseigan perhaps?

I'm dubious about that. If having children disperses one's chakra enough to dilute dojutsu, Hagaromo's Rinnegan would've logically diluted after he sired Indra and Asura, and this doesn't seem to have happened. (Unless Hagaromo's Rinnegan originally had tomoe, like Sasuke's, and lost them; but as much sense as that would make, it doesn't seem to be the case either.) For that matter, if having children weakens dojutsu, how could Hamura awaken the Tenseigan?

And this still wouldn't explain why her Rinne Sharingan was ressurected with her, but the Tenseigan wasn't.
