rustc doesn't suggest adding feature gate attribute to resolve an error

[ghost]

Given the following code: https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=3d9311fa97ed73994120865ed38185e8

trait Foo { }
trait Bar { }

struct A;
impl Foo for A { }

struct B;
impl Bar for B { }

fn func<T: Foo>(arg: impl Bar) { }

fn main() {
    func::<A>(B);
}

The current output is:

Compiling playground v0.0.1 (/playground)
error[E0632]: cannot provide explicit generic arguments when `impl Trait` is used in argument position
  --> src/main.rs:14:12
   |

   |            ^ explicit generic argument not allowed

Ideally the output should look like:
