After due consideration, the Steering Council is in favour of this change, and we are inclined to accept the PEP. However, we’re worried about the amount of churn in this area already, as well as the reliance on a feature new in 3.10 for emulating old behaviour, and so we would like the change to the default to be for Python 3.15 instead of 3.13. Unless you have strong objections to the longer timeline, please update the PEP accordingly, and consider it accepted.
