There was an issue detected on the WLM 2012 survey, where be-tarask wasn't translating the languages while be was. This was due to CLDR not having the country names in be-tarask.
An investigation showed that both be and be-tarask had English as fallback (we have a third variant, be-x-old, but that's a deprecated alias for be-tarask).
User:Wizardist considered that the best way out would indeed be to set the fallback language to 'be'.
Although originated in the toolserver, and on Intuition copy of the fallback rules, such change should be performed at a general level.
