The method name is deceiving, but the test still has value because it tests the internal `FALLBACK` provider. In fact, functions for `BreakIterator` and `Collator` should be fully functional from that provider, as `CLDR` provider does not provide those. Maybe renaming `Compat` to `Fallback` would be appropriate.
