:-) Of course it's not inventing anything, it's just providing a convenient way to commission those servers that can also be driven by other tools. If you bring a lot of server resource on line this is very handy. Juju, for example, can put things on MAAS servers, and one of the things it could put on there is a virtualised environment that could also be managed by MAAS and juju to deploy other workloads. MAAS knows some stuff about the hardware too, for example, how many network cards the machine has and on which networks, which means you can interrogate MAAS to find machines suitable for a given workload.
