   It is useful when reading code to have context about why it is written or behaves the way it does. Some instances in this PR may seem obvious but i think nonetheless offer important context to anyone willing to change (or review a change to) this code.

    I’m not sure that having a comment that references code that no longer exists is all that useful.
