Should wedding showers become a thing of the past?

Reading over Carolyn Hax’s advise column, a commenter mentions that wedding showers are no longer necessary. While in the past, the point was to provide the bride with all the things she needed to set up house and some sexy lingerie, almost everyone gets married later in life now, and already has those things by the time they get married.

Should wedding showers disappear into the the realm of historical trivia, or should we keep having them?
