Well I think it would be the best approach to add backward compatibility 
as most users don't even know on how to install grub via grub-install. 
That is done via the graphical installer Calamares on most Arch-based 
Distributions. Updating the grub menu is common if you install multiple 
kernels or use snapshots via BTRFS.

Simply calling 'fwsetup' is a big NO-NO to me and others. The old 
version runs into the EFI firware or simply turn off the PC during boot, 
which creates boot loops for some or unbootable systems.

I checked on my end with an older grub in /boot and the updated menu.cfg 
script. Only when removing the snippet of 30_uefi-firmware the system is 
bootable again.

Also social media is slowly picking up that issue:
