It's not that easy. Carbon is largely a subset of the classic MacOS toolkit APIs reimplemented in MacOS X to provide a migration path for existing application to MacOS X. IIRC carbonized applications commonly targeted version going back to MacOS 8.6 - 10.x with a single executable. From my unreliable childhood memories the next common range started at MacOS 9.0 (or 9.1).
