PEP 554: Multiple Interpreters in the Stdlib

[Liz (Elizabeth King)]

One thing I’d want to have a sense of is how lightweight starting a new subinterpreter is.

I got shared this: GitHub - ChillFish8/python12-subinterpreters: Some simple and hopefully safe-ish bindings to Python 3.12's sub-interpreters. , which someone seems to have made to get access to subinterpreters from python before an official implementation exists It might give you an idea of how lightweight it is internally.
