Momoshiki and Kinshiki are definitely a threat to Kaguya (the ability to absorb Ninjutsu would be problematic for a primary ninjutsu-user). However, Kinshiki mentions he absorbed his mentor, implying that Momoshiki and Kinshiki are the last two descendants in a long line of similarly-powered people that may once have been truly god-like.

Considering that the plan was to harvest Chakra fruits to process into these edibles, it's very likely more worlds with more shinju exist that Momoshiki and Kinshiki went to harvest before coming to the Ninjaverse.
