What's wild is that with a few minutes of manual editing it would give exponential return. For instance, a lead sentence in your section saying "here's why X" that was already described by your subheading is unnecessary and could have been wholly removed.
That’s pretty presumptive of how obviously the author could improve it. As someone who writes a lot of docs, I find feedback and preferences varies wildly. They may just have well made it “worse” to your preferences by hand editing it more.
