This is what can be found in `eZ/Publish/Core/REST/common.php` (that used to bootstrap the REST services:

```php
'\\eZ\\Publish\\Core\\REST\\Common\\Values\\SectionIncludingContentMetadataUpdateStruct' => new Client\Output\ValueObjectVisitor\SectionIncludingContentMetadataUpdateStruct( $requestParser ),
```

If this value ain't here (anymore ?) I guess the VOV can be removed as well.
