Is a default failAction needed to log errors?

I'm completely new to Hapi, I'm just trying to contribute to another project that uses it.

If I am using `hapi-pino`, is it useful to have a default `route.options.response.failAction` like the following:

```
routes: {
response: {
failAction: (request, h, err) => {
request.log(['error'], err);
return Boom.badRequest();
}
}
}
```

Or without this default `failAction`, will errors still be captured by `hapi-pino`?
