Thanks all.

IESG and IETF don't have unlimited resource. Conclusion of HyBi did make
sense.

As noted by Barry in his mail about WG conclusion and as Mark said, we can
form a supervision again once there's enough interest.

> What *is* in-scope here is how (if at all) that protocol interacts with
HTTP, including HTTP/2; there are several ways you could implement
WebSockets over HTTP/2, and a few pitfalls in doing so that the people on
this list will be able to give you feedback on.

One of the keys of the WiSH proposal is to focus on API level compatibility
with WebSocket. But except for that point, it's a general proposal of
application of HTTP semantics and HTTP/2's power for full-duplex messaging
in the Web. The proposal (one done by Yutaka in 2014 and Van's one also)
heavily depends on what the HTTP WG produces (specs, documents and possibly
any kind of official/unofficial communications). So, I think there
shouldn't be no doubt on need for close work with HTTP WG.

That said, I agree we need to have the right structure of the community to
have the "best" work mode based on various metrics (level of interest for
each proposal, their complexity, scope, etc.), and the IESG and the
co-chairs are trying to do the best in making the right decision, I think.

> However, it's hard to do that before there's agreement in the WS
community about what the requirements are. Ideally, that community would
bring a single proposal that has broad support here for review.

Mark, does this post of yours imply that you're seeing HyBi ML as one
effective representative of WS community at this point with HTTP WG chair
hat on?

Thanks
