Thank you! For me that answers the question.

BTW, I'm glad slides 11, 17, 18 say "Remove user motivations to stick
with BIOS: Improve experience with UEFI Secure Boot". It's incredible
how many UEFI implementations do not offer any *real* BootOrder/Boot####
management even, not to mention the obscure hacks such as forcibly
re-setting the first boot option to Windows, if it is installed etc.
It's no surprise people rely on "shim" and "grub" (and other 3rd party
boot loaders) more than ever -- they want to get out of the crappy
platform firmware UI as soon as they can, and reach a UI they can
actually control.

Thanks,
