The goal is to apply the SCTP protocol as a means to better protect
DNS from source spoofing, resource exhaustion, reflected attack
exploitation, and increased latency.
=> not only this is very arguable (for instance about the resource
exhaustion) but no hop-by-hop/channel security, even something as
strong as TSIG, can provide what we need, i.e., end-to-end/object
PS (*): I use the common meaning of end-to-end, not Masataka Ohta's one.
