I agree; I think it'd be perfectly reasonable to have Recommends on both
mtools and xorriso, but a hard dependency suggests that grub can't work
without them. grub works fine without either mtools or xorriso
installed; one utility, grub-mkrescue, doesn't. There's plenty of
precedent in other packages, especially common packages that many people
will have installed, for using Recommends for packages needed by one of
many scripts within a package.
