Team member @weihanglo has proposed to merge this. The next step is review by the rest of the tagged team members: No concerns currently listed. Once a majority of reviewers approve (and at most 2 approvals are outstanding), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up! See this document for info about what commands tagged team members can give me. |

The final comment period, with a disposition to merge, as per the review above, is now complete. As the automated representative of the governance process, I would like to thank the author for their work and everyone else who contributed. This will be merged soon. |
This was always enabled on nightly since 1.83-nightly (2024-09). We have no feedback since then, so assume it is a low-impact change. This stabilization is targeted at 1.85 (2025-02-20)
