Examples such as http://st.unicode.org/cldr-apps/v#/fr/Category/e9b87f48b668cdf show English code names in plural, but English name in singular form. Some items have English in plural however.
Translating policy seems to always translate the plural from the code name, not the singular from the English name.
Should English name eventually be changed to plural to fit the code name, or should translations always match the English name rather than the code name? The latter would be straightforward if the English name was adapted.
