Mapping object-add to the command line as is doesn't result in nice syntax because of the nesting introduced with 'props'. This becomes nicer and more consistent with device_add and netdev_add when we accept properties for the object on the top level instead. 'props' is still accepted after this patch, but marked as deprecated.
