We are talking at cross-purposes here, but I think we mostly agree. :)

No... I mentioned that zone file transfers are useful mainly for
whitelists, which are likely to be of manageable size and not likely
to be updated very frequently.

I agree that it's probably eventually "game over" for DNSBLs, but not
for DNSWLs. DNSBLs are a pretty effective first-line defense against
spam, but they will gradually become less and less effective as IPv6
becomes more heavily adopted. That just means we'll have to emphasize
different techniques. It doesn't mean doom.
