I personally don't think it is a matter of "use" but a matter of understanding. Someone who doesn't understand biblical oneness just can't get a handle on what God did. Doesn't matter when it comes to salvation, but the oneness understanding is incredible! I've seen it dawn on Trinitarian seminarians, I've taught and it just seems to drive them to their faces in awe and humility.
It is unfortunate that some with this understanding hold it in arrogance and perceived superiority. It is still a wonder to me!
