I can see us having implementation for virtually all devices.

I see what you mean, but no. The fact that libvirt doesn't really store
XMLs on disk for inactive domains doesn't necessarily mean there's no
distinction. The aim of test driver is to mimic real life scenarios as
closely as possible, so that when somebody is developing an app on top
of libvirt they can use the test driver instead of spawning real VMs and
thus test their app quickly. Therefore, the distinction between inactive
and live XMLs must be preserved.
