I thought Earliest Date or Release of Removal is used to record which release we remove the deprecated features. Why do we need a separate table?

Good question! This came from the reason that #6206 (comment) suggests we should not remove deprecated fields from deprecation table. While EOL in the above table indicates the time that we could remove it, the new table targets to note down the time it was actually removed and the latest supporting LTS for that feature.
