Just to be sure I understand: we would have exactly the same problem if we disabled LOCK_DOWN_IN_EFI_SECURE_BOOT in Leap 15.2 kernel-default and kernel-preempt, wouldn't we? Also, I didn't check the code but would LOCK_DOWN_IN_EFI_SECURE_BOOT affect kABI? But even if we could afford it, I'm still not convinced we should because the way I see it, such change would make secure boot essentially useless.
