You're actually arguing against your own point. "Do one thing and do it well" is a great philosophy, and TypeScript actually does that more than Babel does. Babel does translation and polyfill, TypeScript only does translation. Type checking is only done during the translation phase for both tools (using Flow for Babel). So I would say TypeScript is cleaner and simpler in that regard.
