No, the image type had always been efi-raw iirc, just that efi images
now use GPT partitioning, and BIOS booting on GPT drives need an extra
BIOS partition to store the bootloader which used to be stored in empty
space after the MBR headers.  There really wasn't anything EFI at all
about the efi image type before though imo…

Best,
