### Feature Request / Improvement Metadata tables support time travel. Ref: https://github.com/apache/iceberg/pull/1508 implemented using the correct schema for time-travel (schema at time of time travel). This broke time travel for metadata tables , of tables with multiple schemas, because metadata tables have only one schema. A fix is made to always use current schema for metadata tables no matter time-travel or not: https://github.com/apache/iceberg/pull/6980. However, I suggest to implement this feature for metadata tables, whose schema are dependeng upon schema of parent tables. For example, files table readable_metrics column is dependent on parent table's schema, for which column it shows. It would be great to have time-travel work correctly with this, by making files table schema reflect parent table schema at time of time travel. ### Query engine None -- This is an automated message from the Apache Git Service.
