In general connecting all drivers on boot is a performance bug.
I agree in general, but for a QEMU VM specifically, bootable devices can show up and go away at every boot, at wildly different addresses, and there's no way to know about such changes within the firmware (so that we could set the boot mode HOB accordingly). A full enumeration is not super-fast, but it works correctly.
