I didn't change grub-pc/install-devices, and on our 22.04 BIOS MBR + mirrored software RAID servers (of which we have a lot), it has the same value (or the same sort of value, naming the md device). A random 22.04 server install is also using 'super 1.2' for its root /dev/md0 device superblock format, which will have come from the installer since we don't change or customize that. We have some remaining 20.04 LTS servers as well with this same mirrored software RAID root and they are also superblock 1.2 format and the same grub-pc/install_devices setting. I think it has been this way in Ubuntu server installs for a long time (for BIOS MBR, UEFI is slightly different in that it also sets grub- efi/install_devices to the UEFI partitions on the boot disks).
