I've not really thought about the other tools when writing this.

In libvirt we do see much of the same pain points in dealing with
these tools, as we do with QEMU emulator targets though. eg need
to probe features, the complexity of specifying block devices.
So there's clearly some conceptual overlap here to consider.
