The failure on OpenSSL 3.1.3 doesn't seem related to this PR as it's happening on the 3.10 branch as well. Trying to figure out why we're seeing the new failures. |

3.10 branch appears to be failing on OpenSSL 3.1.3, so I don't think that failure is related to this PR: https://github.com/python/cpython/actions/runs/7961486528/job/21732837870 |
I took a look and I agree that merging this looks safe so I will go ahead and do it. |
