The delete.tombstone.handling.mode configuration is missing from the fields returned by the config method of the ExtractNewRecordState SMT. The config method is expected to return all associated configurations for the transform, and products like Confluent Platform rely on this method to render configuration options in the UI.

Additionally, the display name for delete.tombstone.handling.mode is Handle delete records which conflicts with the display name of delete.handling.mode. To avoid confusion in the UI, where both fields would appear identical, I suggest using a distinct name, such as Handle delete and tombstone records
