Note: for device_add command in qdev.json adding the 'allow-init-config' option has no effect because the command appears to bypass QAPI (see TODO at qapi/qdev.json:61). The option is added there solely to document the intent. For the same reason, the flags have to be explicitly set in monitor_init_qmp_commands() when the device_add command is registered.
