Review comment:
For `notifyCheckpointComplete` it's less important because operators are
expected to work correctly even without the notification (and
`channelStateWriter` has only in-memory resources).
Another question: this is a new method and we call it only on RPC
notification, right? Should we also call it in `abortCheckpointOnBarrier`?
