So that's 1) return an (empty) cancellation object even if the server has not sent a key, and 2) error out when trying to cancel with an empty object? That sounds reasonable to me. Are there any reading along who want us to continue sending an all-zeroes CancelRequest if the server has not sent a key? Personally, I don't feel a need to push for that without evidence that it's actually used, and both RDS Proxy and Cockroach [1] seem to fall in the "don't support cancellation at all" bucket.
