If we go the no root element route, I recommend turning this on though so we can use strong params and such in the future:

```ruby
ActiveSupport.on_load(:action_controller) do
  wrap_parameters format: [:json]
end
```

Also, it looks like they have [support for disabling the root element in ActiveModelSerializers](https://github.com/rails-api/active_model_serializers#disabling-the-root-element).
