Comment (by swissspidy):

 > A proper mapping of language codes that can be fallen back to could help
 a bit with both this and performance.

 Why not create a new translatable string for a fallback chain. For
 example, in de_CH_formal we'd say we want to fall back to de_CH,
 de_DE_formal, de_DE — and of course to en_US in the end. This information
 could be translated on translate.wordpress.org by each locale.

 The translation contributors know best which fallback works for their
 locale. We shouldn't force a specific fallback.

 Summary:

 * Core solution with minimal overhead (just 1 translatable string, no UI
 needed)
 * Locales know best which fallbacks work for them
 * Also works for cases like ug_CN -> zh_CN
