I think that the worth of transformation technique as a means to disguise yourself is quite low, since it's a basic technique of the ninja world and thus should be easily recognised by another ninja, yet alone sensors. Regarding its use against Kaguya, it seems illogical to me because Kaguya or Black Zetsu must be clearly one of the strongest sensor types and thus should distinguish certain person from the person which took their appearance (as transformation was never said to change user's chakra signature to the signature of intented target).
