What should be the artifact id of a Turkish localization plugin?

According to JEP-216, the artifact id must include the country code (localization-[language code]-[country code]-plugin), but Turkish localization files inside Jenkins do not contain country code (Messages_tr.properties).

Should I name the artifact as "localization-tr-tr-plugin" and rename all files to "Messages_tr_TR.properties" or is the name "localization-tr-plugin" enough?
