If it is not a sort of therapy you would like to try, then, if it were me, I would get a therapist who would do something I wanted to do. But I would not dismiss something just because it was not approved by the majority or just because it has been dismissed as a placebo effect. Frankly everything they do is a guess - if it works then good.
My partner became super anxious and would start crying and dissociating - that was why they stopped.
