The problem (in my mind) is that some of the perlfaq pages both have links to perldoc as well as old documentation from the site here, which may be what's actually referenced by the link. These are often answers somebody just came up with, and I've found some of them very useful. Removing them could make some links less useful or confusing, and any useful extra information they contained would have to be destroyed (or moved).
