If we want to do that (e.g., if we were to introduce the CLDR concept of meta-zones into the tzdb, so that the CLDR doesn't have to duplicate transition time/date information that's in the tzdb - see the usesMetazone items in metaZones.xml), we might end up creating a new source file format and have a tool that reads the new format and emits the old format.
