I (now) understand that the point of this is to get the most recent copy
(at least of the nodes checked) if all replicas simply haven't been

Thus, the coordinator first contacts the replicas specified by the

data. If you read with less than quorum it would be possible for all the
nodes that respond to have stale data.
