I'm sure you are correct about the knee jerk response of the controller and any PPL should be able to fly a heading. It is intercepting and flying the ILS and reporting established etc that concerns me.
I can see a situation developing where the controller has an expectation of pilot abilities that differs from reality. Considering that a poorly executed go-around will put you in the carpark of the Belgrano it is probably not the best place to be experimenting!
