Not for this particular upgrade, as there is one sequencer, there is no consensus on a price possible apart from a 1/1.

For the future, Iā€™m not in favor of this type of thing in the consensus, as there is no such thing as crypto-economic security for Oracles. Oracles do not benefit from crypto-economic security because misbehaviors are unattributable. Oracles can only use probabilistic models to attribute misbehaviors. And there are lots of problems created by including other types of consensus in the path of the blockchain consensus. There is a good article from Vitalik about it: Should Ethereum be okay with enshrining more things in the protocol?
