You and other relational theorists can define 1NF to be some property of a relation, but I think most people who have ever heard of 1NF (a small subset of humanity) think of it as no compound data, no embedded lists, no arrays ... It is THAT definition of 1NF with which I disagree, while the other definition (the recent one) is not very clear and disconcerting that the entire industry is now supposed to just accept a new definition for the same term. Pick a new term for that property that is inherent in relations and let's discuss 1NF the way we have known it so we can put it behind us.
