One very last counter-argument... Actually, even if we change our default, we are still backwards-compatible, because older libvirt automatically adds <address type='virtio-mmio'/> to the XML. So, all XMLs, created before the upgrade, will have it, so everything will keep working. The only thing affected by the change is domains created after the upgrade. You'll need to specify <address type='virtio-mmio'/> explicitly in order to work with older OSes.
