All device service info should be collected, regardless of whether the message is the last (IsMoreServiceInfo=false) or not (IsMoreServiceInfo=true). The spec does not require that all devmod KVs are sent in messages with IsMoreServiceInfo=true. If the MTU is sufficiently large, all devmod KVs may even be sent in a single message with IsMoreServiceInfo=false.
