I don't think this fix is required. fn start_publishing is only ever called internally. We should never need to worry about an old authorization being passed in.

what do you mean exactly with "internally" here? If I understand correctly, the start_publishing fn is called in the new_payload_job fn that is called by the payload builder service (reth dependency) to start a payload job for the given payload id if not already present.
