Description: 

In Drupal 7 hook_language_init() was used to act right after language was intialized. The main use case for this was overriding configuration settings with localized versions.

In Drupal 8 to provide multilingual settings we have contextual overrides (see #1763640: Introduce config context to make original config and different overrides accessible). There is no facility anymore to hook into the end of language initialisation.
