So what does that thing, tied to EFI as it is, have to do with architectures
where
* firmware is rather unlike EFI
* firmware wouldn't know what to do with GPT
* GRUB is *not* ported to, let alone used
such as, say it, the very first one mentioned at your [1]?
Or is that conditional upon "if anyone wants to design replacement firmware
for those, and if they agree to follow our wishlist"?
