This is a great idea. The workaround is not exactly obvious, most people won't know about it. A contextual menu item is the way to go, either "Reveal In Navigator" or "Reveal Folder" or something like that.
As the author of the other post said: "The rationale here is that photographers often search for an image by its metadata when their actual final destination is the shoot that image came from." Exactly right. 98% of the time when I do a search, the goal is actually to find and open a folder, not a specific image. Having a contextual menu item to open that folder would be very helpful.
