Context

In a Symfony app I'm disabling anything that I don't need. Fragments are one of those features.

I have this config:

framework:
    fragments:
        enabled: false
    #esi: ~

Problem

In the appProdProjectContainer.php container I still see a lot of things related to fragments:

1. Services

'fragment.handler' => 'getFragment_HandlerService',
'fragment.renderer.esi' => 'getFragment_Renderer_EsiService',
'fragment.renderer.hinclude' => 'getFragment_Renderer_HincludeService',
'fragment.renderer.inline' => 'getFragment_Renderer_InlineService',
'fragment.renderer.ssi' => 'getFragment_Renderer_SsiService',

2. Parameters

'fragment.renderer.hinclude.global_template' => NULL,
'fragment.path' => '/_fragment',

Moreover, there are some services that consider fragments mandatory:

<!-- @TwigBundle/Resources/config/twig.xml -->
<service id="twig.runtime.httpkernel" class="Symfony\Bridge\Twig\Extension\HttpKernelRuntime">
    <argument type="service" id="fragment.handler" />
    <tag name="twig.runtime" />
</service>

Solution

I expected all the fragment methods/params gone and the Twig service to use on-invalid="null".
