From the context of the article I don't think the author is proposing removing the default "vacation" functionality of grouping photos by time/location; that could just be one of many modes (e.g. spending several days in a location outside your usual location = auto-group together in an album). This behavior detection is totally possible with simple rules, or modern machine learning. It's one of those ideas that totally makes sense in retrospect. I like the article a lot.
