Depends on the use case. For ML, sure, it doesn't. For web servers, it depends. For stuff like this React-like tool, it matters.

It matters if it's actually meant to be used on the web, but I suspect the use case here is an easy front end for small python program in which case it doesn't matter at all and python interop is critical.
