I never thought it was.

Too many people think "oh, it's inefficient to use more than a bit" but fail to recognize that x86 machine code has a finite discrete set of instructions which operate on finite discrete operand sizes.

It really was time to set up a new platform decades ago - too bad Intel tanked the Itanic.
