Nope. Not sure why whether I am or not is particularly relevant.
Are you?
I am a life-long student of the language, and for those who are, and who use it in their Christian ministries, the difference between using Shen and ShangDi is of great interest and it does matter to know the difference when working with the Chinese in their homeland.
Regardless of the article(s) you cited, ShangDi is not only ancient and pre-Christian, referring to Monotheism in general, it is also in current usage, and even non-Christians in China know that the current usage is referring specifically to the God of Abraham, Isaac, and Jacob, the God of Christianity. There is no other current usage of it.
