String interpolation filling in value instead of compile time error

I tried this code:

fn main() {
    let tup = (500, 6.4, 1);

    let (x, y, z) = tup;

    println!("The value of x, y, z is: {x}, {}, {z}");
}

I expected to see this happen: Compile time error for providing an empty parenthesis in println!("The value of x, y, z is: {x}, {}, {z}");

Instead, this happened:

The value of x, y, z is: 500, 500, 1 The value of variable x (500) was filled in for the empty parenthesis.

Yea, I believe this is a duplicate of #93378 and should be fixed by #93394.
