One quick comment: there's one significant difference between DHCP
options and DNS RR data (RDATA).  In many cases an RDATA is not an
"array" of the same kind of data, like a list of IPv6 addresses (TXT
is an exception).  So I think the analogy of the DHCP option handling
does not apply to an API handling RDATA in a straightforward way.
