I do like the side-effect this produces; namely, joe user can't do a "pseudo ping-flood" by setting a huge preload. We've cancelled a few users for abusing ping in this way to get back at some IRC idiot they don't like. ping -l some-big-number is enough to take down quite a number of terminal servers, and this makes it a bit harder for someone to do damage with a simple diagnostic tool: -|super-g|-$ ping -l 10000 port101.dialup ping: Operation not permitted -|super-g|-$ ls -al `which ping` -r-sr-xr-x 1 root bin 122880 Apr 12 07:53 /sbin/ping 2.1.7.1 allows a big preload value, which I didn't care for...
