The point is that it is more likely to be a "damn, I really needed that 
extra range" situation with 8-bits than for wider widths. Indeed, most of 
the time you'd probably choose the 32-bit or 64-bit type rather than that 
"in-betweener" 16-bit type anyway, as you either really need the space 
efficiency or you go to the "platform word" type.
