The fundamental problem here is that it is securing the wrong thing: it
is securing the computer against changes by its legitimate owner and
user (remember that this is only part of an entire stack of signature
checks). Sure, forbidding unauthorised changes to the system is one way
to stop a class of attacks from progressing, but at what cost?
Furthermore: if an attacker has acquired enough access to replace your
boot loader, you have already lost.
