I assume that some of the delayed shifts and other odd behaviors we perceive are due to this torque management. The torque output of the engine seems to be limited until the transmission fully selects a gear and locks up the TC. I think without that, and the relatively massive, low rpm torque from this engine, we would see a lot more transmission failures due to burnt up TCs and clutches.
I suspect that remapping the engine for more power, and remapping the trans for quicker shifting would result in either a very harsh shift experience, or lots more wear in the transmission.
