 * delivery time is still 'compatible' with the topology in place at send time (eg. a 'get' command cannot execute
 * on a node that is no longer owner after state transfer took place). These commands need to be tagged with
 * the current topology id of the sender so the receiver can detect and handle topology mismatches.
