I used to add i18n on rails apps only when needed, because it forced to create a decent yaml schema for translations (how/where to put keys in the right namespace can be hard). Instead, Elixir/Phoenix uses gettext, you wrap strings with a gettext call, then you run a task and it generates all the files ready for translation. This means I can still use a main language and translate it if needed, without touching the codebase.
