I believe there's consensus that applications blindly relying on
the default machine-type when creating a domain is a bad idea.
That said, can we deprecate this feature in libvirt, encourage
applications to always specify an explicit machine-type, thus
making it possible to deprecate the i440fx machine-types one day?
