Unrequired language pragmas when using GHC2021

If I have a file with a flag turned on by ```GHC2021```, e.g. ```{-# LANGUAGE TypeApplications #-}``` and run

```bash
> hlint -XGHC2021 fileWithTypeApplicationOn.hs
```

should I expect it to pick up the language pragma as unrequired or duplicate?

I'm not currently seeing any warnings but I'm also not sure if that's expected behaviour.
