The Linux kernel acts as an EFI boot loader, if copied to the ESP it
can be directly executed by the EFI firmware.

The initramfs and the kernel live in a vendor sub-directory in the ESP
and are read directly by EFI code, and there is no need for grub2, any
other additional filesystem driver, raid, network setup, or whatever
additional code people think they would need to bring up all sorts of
systems.

The kernel itself with the initramfs can boot everything, has all the
filesystem access which is ever needed, there is no need for anything
else on EFI machines. Even the craziest setups can boot directly out
of the firmware that way.

It's the simplest and most efficient setup a system can have.

And "plain wrong" is the sick game which is called grub2, not mounting
the EFI partition at /boot. :)
