True enough. If password protected GRUB was to be enabled, the
necessary actions/patches should be done so that the users passwords
can be used to unlock GRUB. (Currently only one password can be used
in GRUB).

Gaining physical access doesn't always mean it's done. I mean, just
one use case I have in mind : at an office with BIOS protected
computers, lots of people passing by, I'd rather bet on a five minute
snoop than to bring my screwdriver and start to dismantle my boss
The point is, don't make it too easy.
