One of the different ideas is in
https://lists.isocpp.org/liaison/2021/04/0472.php.

Sure, but once we do this land grab of what the syntax means, doing
the same for C
arrays becomes a consistency fix rather than a novel addition, and the pathways
leading to possible other meanings of the syntax are closed. Which is what the
email linked above is talking about.

At any rate, I'm not advocating either way here, I was just asking
whether we ever managed
to have a liaison meeting discussion about this.
