Yeah, Black Zetsu claimed Kaguya can absorb any jutsu, but we only saw her absorb Amaterasu. When she did, it looked a lot like the time eyeless Madara got out of Amaterasu, though it's really unclear in that scene if he actually absorbed it or just removed his clothes in time, since there was no precedent at the time for anybody absorbing ninjutsu without using Preta Path.
