Symfony 2 Configuration VS Object Calisthenics

I always have a PHPCS live validation of my code with Object Calisthenics rules enabled.
You know, it's hard but helps!

A boring warning always visible is the Symfony 2 Configuration.php where the rule #4 (use only object operator per line) can't be applied if we don't want to go against rule #6 (keep your classes small), so the great and incredible solution is... ignore this warning!

<?php

namespace Acme\Bundle\DependencyInjection;

use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;

class Configuration implements ConfigurationInterface
{
 /**
 * Generates the configuration tree builder.
 *
 * @return TreeBuilder The tree builder
 */
 public function getConfigTreeBuilder()
 {
 $treeBuilder = new TreeBuilder();
 $rootNode = $treeBuilder->root('acme_skeleton');

 // @codingStandardsIgnoreStart

 $rootNode
 ->children()
 ->scalarNode('enabled')
 ->setInfo('Enable the container extension')
 ->setDefault(true)
 ->end()
 ->end()
 ;

 // @codingStandardsIgnoreEnd
 return $treeBuilder;
 }
}

I suggest to use // @codingStandardsIgnore* only when a vendor's code force you to go against the rules, otherwise the rules are useless.
