Did a little searching, and the only thing I could find was this article from 6 years ago.

I'm under the impression that ARM arch is using a couple things that seem a couple years behind, the UEFI thing and Bash not Zsh for instance. Is this because of insufficient maintainers or technical problems?
It occurs to me that I could wrong, and ARM does in fact use UEFI, and my accusations are baseless, in which case I should cite that I've looked at the most recent RPi4 and RPi2 disk images, as of yesterday, and ran `ls /sys/firmware`, and didn't see efi.
