Oops I didn't explain clearly. Take this code:

  pub fn abc() -> usize {
      #[allow(deprecated)]
      "abc".len()
  }

I want it to complain about the "allow", because there was never any deprecated warning emitted in the first place. Maybe it would be called #[expect(deprecated)]

I refactor code all the time and find these stray "allow"s that aren't doing anything anymore
