There is a rumour that Kishimoto didn't know how to make Madara lose to those two; Madara OP Naruto and Sasuke, and then Kishi introduced this turning point: Naruto's new SPSM, and Black zetsu turning against Madara. The final Battle Naruto vs Sasuke was already decided so to make it quick, Kishi introduced Kaguya as a new villain and they both defeated her quickly. I think it's false but it may be the reason as to why he did not elaborate more on Kaguya's life.
