Describe the feature

Hello,

Iceberg version 2 supports dropping columns as documented https://iceberg.apache.org/docs/1.7.0/spark-ddl/#alter-table-drop-column. However, when I drop a column in my source data and try to run dbt, I encounter the following error: "Iceberg does not support dropping columns from tables," as implemented https://github.com/dbt-labs/dbt-spark/blob/0ccce2fdc7f2d6341e3b8fd7630eea516c427b65/dbt/include/spark/macros/adapters.sql#L404-L413.

Is it possible to implement this feature, or is there any blocker preventing it?
