Debiain Bookworm Root on ZFS Guide: missing --no-floppy in grub-install

[nav1s]

I went over the sixth step in the GRUB Installation section.

it mentions to use grub-install --target=x86_64-efi --efi-directory=/boot/efi \ --bootloader-id=debian --recheck --no-floppy for UEFI.
However I wasn't able to find the flag --no-floppy in the grub-install man page.

I think this flag should get removed but I'm not entirely sure why it's there in the first place so I wanted to check here.

edit: to clarify the command did work it's just pretty confusing from a user standpoint
