    OPC UA Part 4 §5.13.7 (TransferSubscriptions): an anonymous session's Subscription may only be transferred over a Sign or SignAndEncrypt channel to a client with the same ApplicationUri. false (the default) enforces the rule; true relaxes it and accepts anonymous-to-anonymous transfers over an unsecured channel (the behaviour before 2.183.0). See OPCUAServerOptions.
