Can you expand on what changes are needed? Only on certain versions of
grub2 can we skip passing the flag IIF it was going to pass it?

Good questions.

My thought is, do the preseed all the time. It won't change the behavior of
older GRUB packages, but won't hurt either. It might make sense to also
continue to do the manual grub-install --no-nvram every time. That will
also be safe with any version of GRUB.

All arches? arm-only?

It only has an effect on EFI and power systems. I know we want it on all
EFI (x86 or ARM). I don't know enough about power to say for sure, but
seems like it would also benefit. Would need to find a power/MAAS person to
confirm.
