> Since the Iceberg table migration will intentionally not rewrite the data files, the migrated table will end up with data files that do not contain the Iceberg field IDs necessary for safe, reliable schema evolution. For this purpose, we should disallow the REPLACE COLUMNS and CHANGE COLUMN commands for these migrated Iceberg tables. ADD COLUMNS are still permitted.
