Probably not exactly what it was designed for, however I see the diversion as a test of whether the student can fly the plane at the same time as focusing on another task.
Even if you are planning to use Skydemon, or some other future method, there will still be a 'task' of some sort that has to be performed at the same time as flying. A task that cannot be fully prepared for.
In real life the situation could be completely different. But if the whole flight test was something that could be prepared for it would lose that element of 'can you fly a plane as well as deal with the unexpected'.
