My point was virtio mmio isn't widely used outside of ARM.
Rather than try to make everyone use it, IMHO it's better

Yes. I would much rather we let virtio-mmio disappear into
history as a random bit of legacy stuff. One of the things
I didn't like about the virtio-iommu design was that it
resurrected virtio-mmio as something we need to actively care
about again, so if there is a path forward that will work with
pci virtio I would much prefer that.
