The indirect methods the Otsutsuki clan used to gain power from their tree would have eventually lead to watering down of techniques/forms/abilities it grants.

As for Kabuto and the Rinnegan:
 * Ashura's power is passed through Senju and Indras power is passed through Uchiha, so Kabuto was right, even if he was overgeneralized. He was wrong about evolving the Sharingan, but it did change the Uchiha eyes into the Rinnegan.
