Anaconda is a for-profit venture, while RustPython seems to be a loosely collected group of FOSS developers wanting to hack on a Python interpreter in Rust. Building a "batteries included" distribution seems like a noble goal but might be a bit too much to chew at the current stage.
For sure, but I don't think it has to be as complete or stable/reliable as Anaconda. Just something that bundles the most popular and important libraries, like requests, httpx, pandas, pytorch, sqlalchemy, fastapi, etc. Stuff that most Python devs are going to want or need, but which they probably won't be willing to spend too much time hacking to get to work with a non-standard Python implementation. Without that, I think it gets relegated to some Fibonacci.py type examples that, while cool, aren't of much use to most devs.
