Yes, machine types are supported by libvirt. In fact each version of libvirt may have a different machine spec, this might cause issues when migrating vms to a new kvm host with a newer machine spec. For these cases its better to be explicit about the machine type instead of setting it to "pc" or letting libvirt chose the machine type. I assume this is why they kept the feature.
