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.
