I think you are making it too complicated.
Someone says, "My neck hurts."
I say, "Oh, try finding the point of tension and see what happens when you put pressure on it."
Option 1: Still hurts.
"Ok. You know the didn't help."
Option 2: It doesn't hurt anymore!
"Great! Carry on!"
I agree that you get into trouble when you try to explain why. (The body is complicated) Or when you become over reliant on soft tissue work.
But if my neck hurts and I find sensitive tissue (I'm fine not calling it a trigger point) and I roll a ball around on it for a few minutes a few times a day for a day or two and the pain goes away, I don't see what the issue is.
I also think some people don't have this soft tissue issue so they don't think it's a thing.
That's okay too.
