This is exactly what I meant by "thin compatibility layer", just
couldn't remember what the exact term was.

I wholeheartedly agree. The only caveat is when the firmware is just
done horribly wrong where in the worst case scenario will only boot
Windows no matter how many times you change and save your BIOS settings
otherwise. LeRoy did not let us forget that. In a past machine of mine
(from 2012), neither efibootmgr nor EFI Shell 2.0 would work; I only
managed to manually add the boot entry for GRUB through EFI Shell 1.0.

The good news is that it sounds like George will not have to worry about
this caveat on his new Dell.
