My point was that it’s not EDK2 instead of GRUB at the same layer: EDK2 is the UEFI layer, and GRUB still runs fine on top of it as an EFI binary from your ESP. All the things you listed keep working that way: LUKS, RAID, password protection, even memtest via the efi/ insert mechanism. What you lose is only having GRUB directly in CBFS without an ESP.

What you gain with EDK2: Windows boots at all, TPM 2.0 works (the SeaBIOS issues that got it disabled are gone), and option ROMs for external GPUs.

edk2 isn’t replacing grub, it is the payload, I have for example edk2 and grub. It is a Uefi which executes the Grub Efi or any other bootloader. E.g systemd-boot or UKI. Btw edk2 is great

when you use the terminal, why use vlc when you can use ffmpeg?

the single problem is when you never codet in rust:(. I am only able to code in C and python an a bit of java

did you tried it, what is the experience like?
