GRUB is simply not necessary on UEFI platforms. All that an OS installer
need do is to correctly write the path to the OS/OS loader into a UEFI
boot variable and the UEFI BIOS handles everything else.

Call me a skeptic, but I very much doubt this.

GRUB fixes the lack of a boot manager in legacy bios. UEFI includes the boot
manager, GRUB is simply redundant.

No. It's not enough in many circumstance, that's why arm64 has UEFI support
still working hard on grub2 port to UEFI. Another problem is you're now relying
on firmware vendor to any bootloader features and that's not possible to
control. Even it has the feature you have, you may have a hard time to do it
twice on other firmware type (or firmware-specific loader) and that's terrible
effort also in terms of integrating them, if your distribution has to support
multiple arch.
