Modeling History Not clean after deleting the body (Beta)

Why are “the related history steps still being displayed in the history panel” after deleting the solid body? In which scenerio do we need those history steps?
Yes, i can select those history steps and delete them manually. But in many cases, i cannot remember which steps were used to create the body, or even cannot identify them when opening other people’s file.

(picture 1 : just select the body only, and delete; picture 2: the result after delete)
