At yesterday's session, Tale confirmed that since BULK adds so much new special purpose complexity to DNS servers, the plan is that support for it will be optional.
An optional RRTYPE with extra semantics introduces some new compatibility problems. What happens if a server that doesn't support BULK tries to load a local zone file with a BULK record. Does it reject the whole file, ignore the record, or something else? What if such a server receives BULK by AXFR? By IXFR? What if one shows up in a cache from a buggy authoritative server? In all of these cases, the current RFC 3597 behavior will just return the BULK record which seems wrong. I continue to think that this kind of feature belongs in special purpose DNS servers, not in the core DNS.
