Yep, that column was indeed never really used. To make the average
case work, one could always update the alias column with the email
address of the default identity once that is updated. But I guess
after introducing the plugin API we can easily drop that column from
the schema and let plugins solve specific requirements.

The option to search in identities as a fall back does sound. Please
just add AND del <> 1 to the SQL query then.

-> use plugins for that.
