I would call this “defensive coding”, analogous to defensive driving. And comments that talk about something that isn’t there is way too defensive, kind of like the excessive braking and overly polite waving that can make 4 way stops so confusing. Write your code clearly, keep your functions wholly visible without scrolling, keep the comments to a minimum, and put the ideas that can’t be expressed as code in a README.
