This should be super helpful, especially for the "reference point and
minimal test requirements" that you mentioned above, along with being
able to boot more distributions in QEMU without fiddling with
kvm_guest.config and menuconfig.

fixed by commit 76366050eb1b ("x86/defconfigs: Explicitly unset
CONFIG_64BIT in i386_defconfig").
