SCTP is 1) not even a sliver of deployment compared to TCP and 2)
doesn't get nearly the same scrutiny on patch review that TCP
changes do.

I basically let the SCTP folks play in their own sandbox, because
frankly SCTP doesn't matter.

The only time I care about an SCTP change is when it has an impact on
the rest of the networking code.

So using SCTP as an example of "see we do this already over here" is a
non-starter.  Don't do it.
