For example, you could easily specify :created_at and :updated_at translations as:
en:
attributes:
created_at: "Created at"
updated_at: "Updated at"
This configuration is built on ActiveModel, so it means those translations are
shared between different ORMs as well (but always as a fallback).
standarize on. Also, in future this place can be used for data/code that's
not literally translations but conceptually belongs to the locale (like
custom pluralization algorithms etc.).
