Historically we did not allow change of behaviour when filling in
defaults unless the old configuration stopped to be supported by qemu
and we could detect it. I don't thik this case can be excused.
Yep, we can't do this, and in any case modern guests should likely
be given virtio-vga instead, which can be decided via libosinfo
rules.
