1. Implementations are free to enable sending or not.
2, Implementations MAY read the ECN code points if they
   can and send ECN ACKs.
3. Implementations MUST accept the 0x03 ACK type and if they are
   sending ECN SHOULD use the ECN section.

I recognize that some people want to have stronger language here, based
on this discussion I think this is where we are. I'll defer to the
chairs to judge whether more is needed here and can change the PR as
required.
