Anyone running a platform that can't take a full table would apply such a filter to weed out anyone who likes to announce all of their space as /24's for "traffic engineering". If one does that and doesn't announce the aggregate as well, one could find themselves facing random black holes.
People are filtering /24s without a 0/0 route?
actually, you should ask the more general question, "Are ISPs filtering when they don't have a 0/0 route?" and i suspect the answer is almost certainly. being default-free has its advantages as does not using some variable RIR metric as a basis for routing policy. --bill
