Support for @cascade and @normalize directives for subqueries

[cyphercider]

Per original thread at: https://discuss.dgraph.io/t/support-for-cascade-and-normalize-directives-for-subqueries/1944

I have a lot of situations where I would benefit from being able to use @cascade and @normalize not at the top level of the query, but on subqueries. Would it be possible to support uses like:

{
  results (func: ...) {
    predicate1 @cascade {
      ...
    }
    predicate2 @normalize {
      ...
    }
  }
}

The error I get when trying this on v0.8.3 is:

"errors": [
        {
            "code": "ErrorInvalidRequest",
            "message": "Cannot have children for attr: [predicate] with lang tags: [cascade]"
        }
    ]

(or similar error for normalize)

Hi, is this one still active. When working serving data to web templates, be able to @normalize at subqueries would make the templates much more natural.

{
  user(func: has(__is_users)){
    uid
    user
    person @normalize{
      name: name
    }
    profiles{
      profile
    }
  }
}

I woud like to map

{{user.user}} - {{user.person.name}}
{{user.profiles[0].profile}}
{{user.profiles[1].profile}}
etc...

Any news on that?

Cascade in subqueries is becoming VERY important to me as I have to build more complex queries
