Check the grubby source code if you're brave. It has a bunch of test cases built into it. But I don't at all understand the reason why Red Hat / Fedora depend on it and no other distribution does, they just regenerate the grub.cfg after a kernel update. Grubby's fussiness came up a lot during the grub2 transition because the syntax was constantly changing in the grub.cfg format, and this would trip up grubby. And it also is presently incompatible with Btrfs subvolumes (Gene Czarcinski has patches submitted to upstream and there are test builds of this version of grubby somewhere in the Fedora build system).
