 * Types 3, 5, and 7 are as of release 0.9.38. See proposal 123 for more information.
   These types should only be sent to routers with release 0.9.38 or higher.
 
+* As an optimization to reduce connections, if the type is a LeaseSet, the
+  reply token is included, the reply tunnel ID is nonzero, and the
+  reply gateway/tunnelID pair is found in the LeaseSet as a lease,
+  the recipient may reroute the reply to any other lease in the LeaseSet.
