Grub and Grub2 count drives starting with 0 (as a BIOS does).
Grub also counts partitions starting with 0.
Grub2 inexplicably counts partitions starting with 1.
I'm afraid I can't go back further than 1996 with Debian (but that was the first release, 1.1 or buzz). At that time, Debian counted partitions from 1, as did lilo. The old Grub definitely stood out in starting from 0, which is why they spelled it out so carefully in the docs, eg: https://www.gnu.org/software/grub/manual/legacy/Naming-convention.html#Naming-convention
Now they have fallen into line, the Grub manual has to make sure you realise it has been changed, eg https://www.gnu.org/software/grub/manual/grub.html#Naming-convention
The most modern fdisk program I have is gdisk (for GPT disks) and it counts partitions from 1. Is there some newfangled disk subsystem that's passed me by which starts counting at zero?
I'm not aware of any that are "newfangled", but all the SCSI hosts I'm familiar with do as does a PC BIOS, count starting with 0, usually making the host, the eighth possible device in a SCSI chain, ID7.
