 The default `statistics_with_args` delegates to the deprecated method, so no
 migration is required until the deprecated method is removed.
 
-> **Warning:** The delegation between the two methods is **one-way**. The default
-> `statistics_with_args` calls `partition_statistics`, but the default
-> `partition_statistics` does **not** call `statistics_with_args` — it returns
-> `Statistics::new_unknown`. So if you migrate a node to override **only**
-> `statistics_with_args`, any remaining caller of the deprecated
-> `partition_statistics` on that node will silently receive
-> `Statistics::new_unknown` instead of your real statistics.
