createSSDXxxPlugin suitable for TensorRT 3.0.2 now?

Some folk discovered createSSDNormalizePlugin functions in https://devtalk.nvidia.com/default/topic/1027502/deepstream-for-tesla/locations-and-classes-are-right-while-confidences-are-wrong-with-ssd-net-using-tensorrt-3-0/post/5226395/#5226395, it all existed in TensorRT 3.0.2, are they ready to use now?
Thanks.

Hi,

These plugin functions are for internal usage.
We don’t have extra information for the public user.

Thanks.

I see, Thanks.
