"important search engine" doesn't mean a new engine. it refers to the possibility that one of the majors could setup shop in a datacenter that has been blocked in the sweep blocks mentioned here.
I already have the fake searchbot problem solved (via modsecurity). What is left to deal with are the other threats, and I have enough measures in place to detect when a rogue dedicated IP is persistent as opposed to one that is doing a drive by script attack. I rather manually block those IPs (or C class at the most) than block entire ranges just because they belong to a hosting company.
