-Symfony component interfaces included as part of the Drupal codebase are used to
-provide Drupal-specific implementations of Symfony subsystems that are not
-available as standalone components and thus cannot be cherry-picked.
-
-A composer.json "replace" entry is used in order to bypass the composer.json
-dependency onto the Symfony components originally including the interfaces
-provided here.
