Tested out locally and it works for me. My benchmarks show a ~100-200ms improvement in the import/start time when manually configuring and ~400-500ms when using the auto-instrumentation. Thank you to everyone who contributed towards this change and I can't wait to see this land 🙌

Do we know when this will make it into a release? Looks like there has not been a release since August, will one be coming soon? I see this in the CHANGELOG.md. It's blocking us from being able to go to python 3.12, so mostly just curious on timing.
