Ah yes, this is what I thought was the current state. I was curious if a GIL removal decision had been made that I had missed, but seems like it's still a soft "maybe":

Edit: And to be fair, you can do "true" concurrency in Python you just have to eject to Multi-processing (with the tradeoffs that implies), so I didn't want to assume the comment was about GIL removal.
