Kuo approved the limitations, which means that you don't have a say on whether or not they can stay.

Also if you read Knowledge Manipulation, there is nothing on there that says it doesn't work on Omniscience.

Plus Knowledge Erasure may work depending on the circumstances.

Erasing knowledge works indirectly on a user of omniscience (as its erasing knowledge from the world/universe/reality), so it considered a valid limitation.
