Each webmaster will have to decide whether the push-down effect of the PICS code at the top of the page is worse than turning away visitors who have the safe-surfing mode enabled.
There are also a couple of directories you can't get listed in without the tag, SafePages and another one, IIRC. Fairly minor directories now, but something to take into consideration.
