Uh, that is absolutely not true on the code issue.

When using the unplug the actuator method, it does indeed trigger a hidden code, which can be seen with the BT (something like an exhaust fume flap error). I have seen it with my own eyes on my BT. There is no code thrown if you do the true "golf-tee" mod by unplugging the vacuum hose and capping it with something.

Having said that, its most likely the dealership will ignore, and I usually don't give it a second thought.
