Okay, not sure what's killing the CI, but ran the following: tox -q -- -q --tb=no -r f, and got this:

  py310-latest: OK (821.05 seconds)
  py310-pre: OK (563.00 seconds)
  py311-latest: OK (673.70 seconds)
  py311-pre: OK (616.78 seconds)
  py312-latest: OK (648.87 seconds)
  py312-pre: FAIL code 1 (163.71 seconds)
  py313-latest: FAIL code 1 (21.53 seconds)
  py313-pre: FAIL code 1 (3.26 seconds)
  py310-min: FAIL code 1 (111.14 seconds)

Seems like more of a versioning nightmare than an issue with this PR, but haven't investigated each part of the testing matrix that failed as of yet. Use your own judgement on whether to merge this or not.
