TCPINC is a case study in bad decisions that IMO we should not try to
repeat, from insufficient pushback on option squatting, to use of
out-of-band data in the SYN payload, to assigning a new option to an
experimental protocol, to not actually protecting TCP itself (except in
a very small subset of control info).

In all cases, my position on these issues has not changed and I will
continue to oppose them.
