It is usually better for performance not to create a DELETED() tag, even though it causes the query to be only partially optimized if SET DELETED is ON. The reason for this behavior is that if you are operating over a network and few records are deleted, bringing the DELETED() tag over the wire can take a non-negligible amount of time for very little gain when compared to just testing the deleted status of the fewer records in the result set.
