this could get horribly technical, but i can see why they haven't
threading is most useful when you have multiple tasks to do that are independant
of each other. Unless you have a TM1 model where no cubes have rules or TIs that make them reliant upon each other, or share the same dimensions, i can't see how they can make proper use of threading. It would have to try and calculate 2 cubes until it found a dependancy on something then wait before continuing. How the blazes could they work that out when they can't write automatic feeders?!
If this were a dictatorship, it would be a heck of a lot easier, just so long as I'm the dictator.
