> In 1.16 we now allow the cluster flow to be modified while a node is disconnected, or in any other state except for CONNECTING. We should also not allow the cluster to be modified while a node is offloading. If we do allow the cluster's flow to be modified while a node is offloading, it's possible that a connection will be removed while the node is offloading data to that connection, and the node will never complete.
> At a minimum, we should disallow deleting a connection while a node is offloading.
