After discussing PEP 734 before and during PyCon, with you and many others, and confirming with @hugovk that he will issue a feature freeze exception for Python 3.14, the Steering Council approves [PEP 734](https://peps.python.org/pep-0734/), with one suggested change (see below). The Python community is incredibly grateful for your diligence, tenacity, and expertise in bringing the subinterpreters feature to fruition. Despite the Zen of Python’s “There’s Only One Way To Do It”, we believe that giving Python developers options for parallelism is ultimately in their best interest. Choosing which mechanism to use for concurrent programming in Python is a complex decision, and subinterpreters brings an important and useful option to the table. Besides that, all the work you’ve done “under the hood” has helped improve Python in general, and that is also greatly appreciated. We have one request. We think rather than adding a new top-level `subinterpreters` module in the stdlib, a better place for it would be `concurrent.interpreters`. This should make the module easily discoverable, and it gives more validity to the [`concurrent`](https://docs.python.org/3/library/concurrent.html) package. We imagine that if we add additional APIs for free threading in the future, they might also go under the `concurrent` package. If you’re agreeable, then congratulations! Please update the PEP accordingly and coordinate with Hugo on any PRs requiring an exception.
