You would own the smart-contract release train, external audits on every release, and our diff against upstream Optimism: what we take, what we hold, and where we diverge on purpose. You would also explain the chain's unexpected behavior to people who are not protocol engineers. The pool of people who can do this is small. If you are near the edge of it, apply.
