It is absurd for any user to use a half baked Python interpreter, also one that will always majorly lag behind CPython in its support. I advise sandboxing CPython instead using OS features.
Python already has a lot of half-baked (all the way up to nearly-fully-baked) interpreters, what's one more?

The repo does make a case for this, namely speed, which does make sense.
How do I sandbox CPython using OS features?
(Genuine question, I've been trying to find reliable, well documented, robust patterns for doing this for years! I need it across macOS and Linux and ideally Windows too. Preferably without having to run anything as root.)
