The strategy behind JavaScript is to write your application as close to one time(s) as possible. Adding Python or c++ defeats this goal. For most startups looking to build their MVP, the cost of c++ dev (in addition to writing your codebase a second time) would be dangerously unpredictable in cost and stability if they're not already using c++. Python is missing strong alternatives to both writing UI code in the browser and alternatives to react-native. It's also not reliably faster or better than nodejs in any metric outside of a few unrelated top libraries like numpy and ML. The JavaScript community is also interested in an electron alternative and proper QT bindings to nodejs would be a valuable first step to solving the electron problem, if another solution isn't established via react-native/native-script.
