The nature of Garden is to support container managers as Garden backends. Garden itself is just a client/server API spec.

For example, [Guardian](https://github.com/cloudfoundry-incubator/guardian-release) is in the works to replace the Linux backend with a thinner runC-based backend.

The main value we get from it is having a nice Go API and not having to overhaul everything using Garden every time some shiny new container tech comes out.
