To say that another way: vendors who produce such devices are failing
to follow the Postel principle. Whether the IETF says anything
explicitly or not, they're producing artifacts of less value to their
customers.  Standards-compliant stacks will emit TCP options in ways
that such vendors evidently don't expect.

The IETF standard reflects a consensus among designers and
implementers that there's no constraint on TCP option ordering.  The
time to argue about it is past; live with it or produce crappy products.
