Of course. Their time is limited, and they spend it on more important matters: how to get better stories, how to detect voting rings, how to eliminate randomness of whether stories are upvoted during their short time in the /newest queue, etc. I'm happy they spend their time working on what matters; unknown/expired link is a nonissue in comparison.
