The author says this is a simple change and shows it is equivalent in the database, giving examples such as equal, arity zero, and isRelation false. They also indicate they reviewed the database (Rome and Obsidian) and found nothing on the website, stating the change is exhaustive since arity is gone. The conclusion is that they can now depend on isRelation."}
