The advantages that I perceive aren't necessarily the ones that are
touted on the various grub2 tutorial pages (which seem to be
modularity, flexibility, and portability).

. booting from an ext4'd /boot (which isn't possible for a
non-Fedora-patched grub1)
. booting from an lvm'd /boot
. rescue mode (if stage 1 - boot.img in the 1st sector - loads but
stage 2 - core.img in the next 62 sectors - doesn't load, you can get
to the grub menu at the cli with a reduced number of available grub
commands)
