That's a lot of "if"s.  It is quite common for primary and secondary 
providers to have only a loose relationship, and they do not know or care 
about their detailed capabilities.  I swap secondary service with a bunch 
of other people I rarely talk to (no need) and if they started sending me 
BULK records, the results would not be good.

It seems like you are assuming that everyone will eventually support BULK. 
I see no reason to assume that -- for those of us with small systems, and 
who do not want to do generic 6 rDNS (see draft-ietf-dnsop-isp-ip6rdns) 
it's just bloat.  This means it'll always be optional, and optional DNS 
features present new operational issues that we haven't begun to address.
