The first issue was noted by Jason: We need to care about changed ring sizes. We also want to support different ring sizes in ccw for virtio-1 devices (existing code did not propagate changes to core). The final patch enabling virtio-1 support also introduces a new property that allows to specify a maximum revision. I don't see a need to fence off legacy; the maximum revision approach instead allows us to easily introduce new revisions and still cap at a revision for compat machines.
