Issue Description

I was looking through the L2OutputOracle.sol and on this line the comment says the address of the Proposer can be updated via upgrade. It also says something similar for the Challenger.

I was curious how an example of updating either address would look like? Is it basically upgrading to a new L2OutputOracle logic contract that has a setter function to set a new Proposer/Challenger? If so, why is this comment only present on the Challenger and Proposer variables (presumably you can do the same to all other variables stored in the contract) ?

I believe upgrading them would require deploying a new logic contract. Then, the address of the executing contract should be updated in the proxy contract.

This is correct, we don't have any public documentation on this yet, but I'll create an issue on the docs repo. You'd accomplish this with the proxy admin wallet. Docs on privileged roles
