The EFI boot loader is a different beast — the notion of “boot blocks” doesn’t even really exist in the EFI environment.  The boot loader is just a program, like any other EFI program, that just happens to be loaded by EFI when the operating system is booted.  There’s no stuffing the right thing into a special sector on the disk.  It’s entirely reasonable to expect to upgrade the boot loader when upgrading the operating system.
