No one has touched this.
To me, this is the crux of scripture as text, and the problem of historical belief.
I seems @Hamilton Porter did a pretty good job of responding to your line of thoughts. He is saying that religious history is very meaningful for prophets and other heroic characters that wade through much tribulations and serious testing. We see this in the life of Jacob (son of Isaac) where his whole life was a long series of progressions and challenges and seasoning. Same for Abraham and Jonah and even Mahonri Moriancumer (brother of Jared) and many others.
ALL of these things are REAL experiences intended for everyone that is born into a fallen world. Which is the essence of the Plan of Happiness. Very necessary to be able to advance beyond what we achieved in the pre-existence.
The scriptures (religious history) is extremely important for learning the testimonies of actual historical persons. It is an encouragement for the readers to exercise greater faith in applying incremental steps in drawing closer to God. For some it may require willingness to give up their lives in order to remain true to the Gospel.
We don't necessarily need to "worry" about Bach's biography for the purpose of evaluating his music. But information about his background, the mentors, the music of his "competitors" and cultural influences are interesting to scholars and lay people. The same holds true for eminent scientists who stand on the shoulders of giants that preceded them.
