Why does the GT-R have transmission clunks and noises? Feature or flaw?

The Nissan GT-R's unique transmission behavior is one of the most talked about aspects of the car. As is well documented in reviews and by many owners, the car's dual clutch transmission produces a variety of clunks, whines, and other mechanical noise when traveling at low speeds, or when shifted into reverse. Others say these noises are just part of the GT-R's character and the nature of the GT R's performance oriented design. They say it's a flaw that detracts from the whole experience and makes the car seem unrefined than its rivals. But the debate often stems from: do these transmission quirks enhance the GT-R’s raw mechanical appeal, which is to be expected from Nissan’s straight up supercar, or are they just pure annoyance that Nissan should have fixed in later model years? As GT-R enthusiast discussion turns to the topic of this car's refinement and usability in terms of everyday driving this topic constantly arises.
