 Feature: Create a translation of an article version
-  A user who can create articles adds a version of an existing article in another language. The version joins the story of the version it is created from, in the same site, as an offline draft. Two entry points share one implementation: POST /v1/article/{id}/translations and POST /v1/article/ with story_id. Hidden versions are never named, counted or hinted at.
+  A user who can create articles adds a version of an existing article in another language. The version joins the story of the version it is created from, in the same site, as an offline draft. Two entry points share one implementation: POST /v1/article/{id}/translations and POST /v1/article/ with story_id. The story_id entry point is deprecated: it keeps working with the same results, and new clients use POST /v1/article/{id}/translations. Hidden versions are never named, counted or hinted at.
