What makes you think it's potentially irrelevant? Go by any mental health clinic in your city and ask if there are any patients who have conditions that impair either their ability to come in for treatment or their ability to recognize that they need treatment. I agree with the majority of your rebuttal that, at the moment, it's more productive to focus on simply getting this new treatment to a point of reliable functionality. But that doesn't mean that its potential secondary effects on patient treatment outcomes shouldn't also be considered or explored during experimental trials.
