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.
