After dealing with UUNet security regarding several smurf incidents I asked them this same question. Their response (and I'm sure it would be the same response of others) was that a lot of the routers on their network couldn't handle the load of using CEF-CAR to limit smurf attacks.
The explanation I got from uunet regarding smurf attacks and why they dont shut down their smurf amplifiers when notified repeatedly about them, is that their ascend tnt's dont support icmp filtering.
