Yep! The JS output is different for each! In `react` `createElement` is used, with arrays or singleton children. In `react-jsx`, the `jsx` and `jsxs` ctors are toggled between based on if the child is detected as singleton or not (in addition to array/no array in the actual argument). In `react-jsxdev`, the `isStatic` parameter passed to the ctor is changed based on weather a singleton child is detected or not. So there's meaningful output to check for all 3!
