What has not yet been accepted is your proof of this "fact." It is 100% your assertion that A and B are functionally the same, but as I've noted, you're using behavior of languages that have a first-class value of "undefined" to assert something about a language where there is no such first-class value. Your premise that zsh's default behavior is not internally consistent is based on that assertion. I'm curious to see your proof, but it's unlikely to convince anyone who currently disagrees with you to undertake alteration of the default behavior.
