Thanks! Wow, that came around quickly.

I had to think this through again, but I think this is correct: this is a deprecation for Python 3.16, which will become stable in autumn 2027, around the same time that Python 3.11 goes end-of-life. That means that the deprecation warnings will start to be emitted at basically the same time that the lowest non-EOL Python version is Python 3.12 -- and Python 3.12 is the first version in which users can use PEP-695 syntax

the test failures from the deprecation warnings in setuptools in https://github.com/python/cpython/actions/runs/26230364757/job/77188896358?pr=150190 do seem a bit concerning. Do we need to update setuptools before landing this?

We can address the setuptools.whl tests failures in two ways:

  1. We can update the bundled .whl to a newer version
  2. Or we can add warnings ignore guards

I think that both have their downsides, but I would probably go with 1 :)
