[libvirt] [question]Why libvirt bind all devices with same vendor id and device id to vfio-pci driver, and only unbind devices used by VMs to original driver?

Hi, As the title says, I thought that it's a bit unreasonable and inconsistent to unbind devices assigned to VMs to original driver and leave other devices binding to vfio-pci driver. Why not to bind devices we need to vfio-pci driver instead of bind all devices with same type to vfio-pci driver? Or, we may can rebind devices unused with same type to original driver.
