Well, to be fair, such a bloom-filter based approach helps not only
people who have unsigned zones but also zones using NSEC3 opt-out and
people using minimally-covering NSEC records (RFC 4470) - which I think
CloudFlare is using some variant of.

Perhaps the bloom-filter idea is something that should be explored
after all (although I admit I don't see the relation to the unsigned
NSEC3 approach)?
