At least that's what I think people would be concerned about in going UEFI over BIOS. Of course, I'm probably just projecting.
..but BIOS is a mostly 20+ years of legacy code hacked together so it works. It is less reliable because changes are transparent and you always have to worry about breaking something.

BIOS isn't simple.... if you look behind the scene. Simple changes can break backwards compability to obsolete functions.
BIOS is also slooooooooooooooow.
