Does a search warrant specify only the residence and stop at the residence's threshold to the backyard or curtilage?

United States v. Ross, 456 U.S. 798, 821, 102 S.Ct. 2157, 2171, 72 L.Ed.2d 572 (1982). We are unable to identify a privacy based reason why this principle should be restricted to the inside of a residence and stop at the residence's threshold to the backyard, or curtilage. If a search warrant specifying only the residence permits the search of "closets, chests, drawers, and containers" therein where the object searched for might be found, so should it permit the search of similar receptacles located in the outdoor extension of the residence, i.e., the curtilage, such as the container in this case. To hold otherwise would be an exercise in pure form over substance.
