Open loop doesn't preclude this stuff; in fact, I think many of the aftermarket systems like the PCV require going open loop. Whether the stock or modified system is better in the qualities you mention is open to question since we don't have a US tune bike yet. And I don't know how much attention this bike will get from aftermarket tuning specialists. Fuel mileage will probably go down a bit.
My guess is that you can bolt on this system and the bike will run fine. Whether it will run better/worse than stock with/without aftermarket turning, hard to say at this point.
