These aren't new projects... just rebranded versions of half-baked feature proposals that I thought were still being reviewed/discussed. I guess somewhere a decision was made to move forward regardless of community concerns?

Baking these features into Docker is the beginning of the end of Docker's Enterprise story. Moving forward with these proposals guarantees the rise of Rocket and other Enterprise focused containers. Docker is forking its own community here.

Both Machine and Swarm are not baked into Docker – they are separate projects and binaries:

Compose is still in the design proposal stage. We want to hear whether you think it should be built into Docker or not: https://github.com/docker/docker/issues/9459
