Over time I've changed my mind regarding the GIL. Now I think it's existence actually is a good thing, since it makes a lot of things easy and robust by default.
The subinterpreters route sounds really promising since it strikes a good balance between allowing those that need same-process parallelization to be able to do so and keeping the status quo (like workers in Javascript).
I'd actually veto PEP 703 at this point, since the Python optimization team is making good progress, and this could actually take them back a bit, while diverting too much energy into a low-reward avenue.
