I agree that this is a serious scenario that everybody using block lists
should be wary about.
But I am not fully convinced that it justfies the strong warning
grub2-setup emits, let alone the conclusions the Fedora team drew from
it. After all, this scenario requires the user to make a serious mistake
as root, and we all know that this can have all kinds of really bad
consequences.
AFAICS, for extX/Linux at least, there is no risk scenario that doesn't
involve this kind of serious user mistake.
