I can agree it strictly limits the type of attacks that can be done, but it doesn't appear to be any practical increase in security. It's like arguing for adding another step in the manufacturing process of bulletproof armor to add a few extra atoms to the armor's thickness. Sure it theoretically adds some protection against some 0.000...1% of bullets that would have just barely had enough force to get through, but it wouldn't have made a difference to any single previously observed successful attack of a similar nature. The fact that someone would argue that this increase in defense is good enough to obviate the need of switching to a different type of stronger defense seems to imply a misunderstanding of hashing.
