I left two nits but the actual changes look fine to me. Can you please also:
- Update the PR title so it better reflects the purpose of the change, e.g. "Reduce garbage in deprecation logger" gives readers a much better understanding what this change is about than a more generic title.
- Update the PR description to indicate how much we gain from that?
