For those wondering what PEP 703 is:
CPython’s global interpreter lock (“GIL”) prevents multiple threads from executing Python code at the same time. The GIL is an obstacle to using multi-core CPUs from Python efficiently. This PEP proposes adding a build configuration (--disable-gil) to CPython to let it run Python code without the global interpreter lock and with the necessary changes needed to make the interpreter thread-safe.
Yes, there is an issue. I wouldn’t expect the core devs to implement this soon since currently all of their time is being spent on core issues like scalability and bug fixing. Most new features seem to come from contributors. A bug bounty might be a way to incentivize someone adding this feature.
