I guess I see what you mean if we want to get very technical about what a syntax extension is. But I think for the purpose of this discussion, it's reasonable to think of macro_rules! as a part of the Rust language. Practically speaking, it is syntax provided by the language team, not just users of the language who are free to extend the syntax by using macro_rules! to do so.
