The reason for adding this to the EFI executable on ISOs is so that 
those same ISOs can be installed to a VFAT USB stick and that USB stick 
bootable via EFI.  The particular use case i'm thinking about is 
Ubuntu's usb-creator. It extracts the ISO directly to the stick.  If the 
EFI executable contains these two modules, no additional work is necessary.
