@ianswett 
> I don't think we can enforce this any more than we already are, so I believe implementations should function relatively well without receiving SETTINGS.

Yeah. We have seen interop fail between some endpoints due to one side expecting SETTINGS before sending the request (response).

I would prefer sending the settings parameters using EE, _if_ we are to also require the server to wait for SETTINGS before sending anything. That would make the protocol design simpler, because transmission of any frames (expect the settings parameters) can be based on the knowledge of the peer. Admittedly, I am referring to [our discussion at IETF 103](https://github.com/quicwg/wg-materials/blob/master/ietf103/minutes.md#settings-interlocking-slide).
