I'd like to discuss the logging tag choice. While I understand the consistency argument for using (gc,ergo,heap), I believe (gc,sizing) is more appropriate here because:

1. This is a distinct sizing mechanism, not traditional ergonomic heap management
2. Users troubleshooting time-based sizing specifically will benefit from a dedicated tag
3. It aligns with the feature name and purpose
4. It provides better separation of concerns for logging

Would you be open to keeping (gc,sizing) for semantic clarity?
