Suppose I have a query say
mutation{xyz(abc:xyz){identity{uuid}}

When I try to fetch the projection from the datafetching environment by using 
  Map<String, List<Field>> projectionItems = environment.getSelectionSet().get()
  
  In version 6.0 I get something like
  
  identity=[
    Field{
      name='identity',
      alias='null',
      arguments=[
        
      ],
      directives=[
        
      ],
      selectionSet=SelectionSet{
        selections=[
          Field{
            name='uuid',
            alias='null',
            arguments=[
              
            ],
            directives=[
              
            ],
            selectionSet=null
          }
        ]
      }
    }
  ],
  
  
  while with same query but with version 9.0 I get something like
  identity=[
    Field{
      name='identity',
      alias='null',
      arguments=[
        
      ],
      directives=[
        
      ],
      selectionSet=SelectionSet{
        selections=[
          Field{
            name='uuid',
            alias='null',
            arguments=[
              
            ],
            directives=[
              
            ],
            selectionSet=null
          }
        ]
      }
    }
  ],
  identity/uuid=[
    Field{
      name='uuid',
      alias='null',
      arguments=[
        
      ],
      directives=[
        
      ],
      selectionSet=null
    }
  ],
  
  
  
  this identity/uuid object is extra in the 9.0 version. I just want to know what is the significance of the this extra information.
  Apart from that is there anyway to surpress this extra information I mean although I can rewrite the projection to JSON array 
  conversion but still what is significance of this information.
