Nowadays? Almost no scenario is worth the hassle. Seriously.

IIRC the main reason in that past was:
- to ensure you have a working domU (since you'll only be using kernel
and initrd from dom0, which presumably is well-tested by the admin)
- to NOT use pygrub (there was some security hole)

Just stick with pygrub/pv-grub, and use compatible /boot on domU (or
/, if you keep it all in one). Some old pygrub/pv-grub require you  to
use ext2/3 for /boot, while newer ones should handle ext4 just fine.
