I don't see how MDMA can be useful for exploring relational issues. It's primarily a controller of emotion and mood, not a psychedelic.
So all it's going to do at best is make a client artificially imprint on the therapist - because the client would experience intense emotional closeness after it was administered, followed by a real downer after the session.
I'd consider that abusive by definition. It's certainly not going to have the much broader and risky but potentially more productive ego softening effect of real psychedelics, which would focus much less on the therapist and more on the client's interior world.
