Yes, and good engineering is also the art of simplicity; we should also respect engineering work by the amount of useless code they didn't write. Docker resonates well with people because it focuses on aspects of virtualization that people care: development and deployment. It alleviates the need of using complicated configuration management tools by providing layered images, and encourages fine grained containers by supporting first class volume sharing. The fact that it integrates well with other virtualization stacks is a proof that for a good part it's orthogonal to them.
