We are only wrapping the Docker CLI, not forking the full code (that would be insane). The wrapper is provided for convenience since it should be enough for most users. If you know what you're doing, you don't need to rely on the wrapper, we explain how you can do that on our wiki: https://github.com/NVIDIA/nvidia-docker/wiki/Internals

Yes, we have been discussing with a few people at Docker, I hope attending DockerCon and discussing with the team will help us move forward.
