class RegisterSerializationClassesCompilerPass in Drupal 9

Adds services tagged JSON:API-only normalizers to the Serializer.

Services tagged with 'jsonapi_normalizer' will be added to the JSON:API serializer. No extensions can provide such services.

JSON:API does respect generic (non-JSON:API) DataType-level normalizers.

@internal JSON:API maintains no PHP API. The API is the HTTP API. This class may change at any time and could break any dependencies on it.
