grubby wraps multiple bootloader configurations.  grub, grub2, yaboot, and
possibly one other.  While it might be reasonable for it to just run
grub2-mkconfig if it detects grub2 installed, it's still needed for the
other bootloaders that are used in Fedora.  Otherwise the kernel spec
would need to handle all of this directly instead of calling grubby.  That
sounds like a nightmare.
