Totally agree. It is impossible to show why one tradeoff was chosen over another without comments. Is there a loop unrolled for performance reasons? Is there a design goal that looks complex on the inside, but yields a simple, easy to understand API on the outside? I feel like "good code is self documenting" is a pitfall that devs always fall into believing on their journey to becoming a "Senior", and then somewhere along the way run into their old "good" code and can understand what it does perfectly well enough, but cant recall the circumstances that led them to arrive at the choices they made in writing that code.
