+1, This has been my interpretation too, I feel like a lot of the rkt PR was subtly aimed at Docker, it was very much "this is why it's better" rather than "this is why it's good".
Honestly, as a consumer of both projects, I'm happy that rkt exists because it provides a working demonstration of a solution where container images are orthogonal to other concepts such as orchestration. If it went the other way, our vendors would be swearing up and down that the only way for this container thing to work is if we install their complete solution.
I love my Apple MacBook Pro and its soldered components, but I need my data center to be meaningfully upgradable.
I love Docker, but it feels a lot like the days of incompatible VM images, where you got super locked in, and if you tried anything that wasn't what they had designed for, then you got screwed.
