IMO there's no real point modifying any of the spirituals listed in the DT except possibly to clarify that whatever is listed (tune or text) is "just one way" of doing that piece-- because they are so endlessly combinable and have often been so conflated in choral arrangements, and can be further conflated for any style of performance, that it just doesn't matter.... the genre is based on improvisation anyway, and there is no "right" version-- no one, no where, no how.
