One possible solution would be an EDNS signal indicating whether or not the secondary server implements BULK. If not, the primary would have to expand the BULK data during transfer, same as BIND expands $GENERATE.
That doesn't work -- this is intended to generate rDNS for IPv6 and other places where you can't possibly store the full expansion.
