Because grub has no control over what happens. But isn't the question about a real world corruption scenario legitimate nonetheless? And who else but the GRUB developers would be able to answer it? Upstream possibly underestimates the unsettledness that the strong wording of grub2-install's warning and the constraint to allow block lists only with "--force" has caused among users and other developers. The Fedora developers took this warning so seriously that the option of installing anywhere else but in the MBR has been removed from the installer. > grub2 does not stop you from doing it.
