This change proposal would only be x86_64, since that's the platform where we need to solve the unsigned initrd problem with SecureBoot with EDK2/QEMU (and more generally with bare metal, but this change is limited scope to VMs to make it tractable to pre-built initrds with a fixed set of kmods). While aarch64 uses UEFI, there's no viable SecureBoot support for it in EDK2/QEMU yet. If and when that appears, then it could be extended to aarch64 at that time. There's no plans for ppc64le / s390x. NB, I'm talking from the POV of what we require to address as virtualization platform maintainers. There might be other use cases for UKIs from other teams TBD.
