I suppose for the same argument that can be made for single-language-but-inefficient configuration systems. When you're doing a basic process, reliability >> efficiency. And sometimes more pieces in your stack just decrease reliability of the entire system. (Admittedly! Rolling your own version of an already well-implemented stack component is not without its peril as well)
