Now, if a malicious validator set publishes a malicious `Batch` at the last moment, it'll cause all future `Batch`s signed by the next validator set to require a bool being set (yet they never will set it). This will prevent the handover. The only overhead is having two distinct `batch_message` calls on-chain.
