Presumably you have another patch which auto-adds a 'dmi-to-pci-bridge' device when we see a q35 machine, so that auto-PCI address assignment still works ? If we relied on the user to add that device, then legacy apps will not work against a QEMU which defaults to q35, since they'll be adding PCI devices but not know that they need to add this bridge.
