I never said FastBoot takes 90% away. But it is the example of how simpler things can help firmware be faster and more efficient. I have quite an experience with legacy BIOS modification and RE, UEFI modification and RE, and coreboot development. So I know what I am talking about. One more example of such overengineered thing is the ACPI standard. Especially, since 6.0 version it is tied up to UEFI. EUFI was not designed to be open anyway since it effectively hides the hardware initialization (PI stage) in binary blobs.

UEFI is a beast from the worst times of Microsoft and Intel - this is why it uses PE (Portable Executable) as a format, didn't even bother for optimization, that caused some of the vendors to invent TE format (Terse Executable), which is leaner a bit. And the code, the EDK1/EDK2 code is a perfect example of poorly-written code. Compare it to coreboot or Linux kernel codebase.
