Re: [tcpm] call for feedback on SYN-EXT-OPT draft

Hi, Yoshi,

We had done some tests when the draft was submitted, but that project is no longer active.

Note that this is “if it works” safe, i.e., if the packet fails through a firewall or NAT, it simply means that the space in the SYN won’t be extensible.

At the moment, it seems like QUIC has solved the burning need we had for TCP options space, by attracting all the work that would normally need more options. However, after many years of discussion about how to handle this for TCP, and many candidates, the EDO approach was the one the working group was able to get consensus around, and we really should wrap up and publish it, IMHO.
