Such a partition couldn't hurt with DOS tables, too (I think there isn't a way to mark the partition table type as such in msdos tables, though? So maybe it can't be done / done easily.) Basically, on msdos partitions, there's usually a post-MBR "gap" where there are no partitions and a part of GRUB is put there. It can't be put in a filesystem because filesystems can shift their files around, and it's loaded by the <512 byte MBR, which can't be very smart. GPT tends to fill up all the space you'd have a post-MBR gap in, so you have to do the more-explicit-and-reasonable approach of making a partition for the GRUB data (in GRUB2 we call it core.img).
