In order to harden the node for the main network deployment, we should remove all APIs that are related to the P-Chain and the X-Chain. This will avoid that anybody could find an exploit to mess with the network by using these two chains, which will be completely irrelevant.
After removing all of the APIs, we might also be able to remove a lot of the underlying code that exists to serve these APIs.
