Thanks for your question.
You could definitely use a D7 if you wanted in this backup, there’s nothing that rules that out in hymns and nothing harmonically that would make the D7 not work.
This just came down to personal preference in this case, a D7 has a little more tension harmonically (because of the C note) than just a standard D chord. I just enjoyed the sound of the standard D chord when I wrote up this backup arrangement.
But there’s definitely times when I’ve played this song and added a D7.
If you have any more questions let me know.
