Review Comment:
@kevinjqliu That's a great question. According to the spec, there is no
difference:
<img width="855" alt="image"
src="https://github.com/user-attachments/assets/e7b842ff-83e8-4711-933d-355b4fb07cb5";
/>
There are some more examples: `"snapshot-log":[],"metadata-log":[],`, maybe
defer that question to a separate PR?
