Out of the box vue-i18n does fallback lookups for messages by trimming off parts of the <language>-<region>-<dialect> locale label. This means that a hypothetical locale of de-DE-bavarian would look in:
We can configure fancier fallback chains using a fallbackLocale map.

Change 651556 had a related patch set uploaded (by BryanDavis; owner: Bryan Davis):
[wikimedia/toolhub@main] i18n: Configure fallback locales for vue-i18n
Using the sed command from T258492#6490574 I have been able to extract a collection of fallback rules from the MediaWiki code and create the map included in https://gerrit.wikimedia.org/r/651556.
One thing to note with this, we should take fallback chains into consideration if we start lazy loading locales in the future. This would mean doing some lookup of the fallback chain when switching locale and loading all the locales in the chain. Not an impossible thing at all, but something to keep in mind for the future.
