Hi @avayvod,

> Since sending and receiving messages to/from a "connecting" 
connection might sound confusing, and w/o this extra functionality 
"connecting" state doesn't add much, maybe there're other ways we 
could workaround passing the metadata etc?

While there may be better ways to expose messaging channels, 
consistency across similar specs seems like a good idea.

Typically, both WebSockets and WebRTC data channels have `connecting`,
 `open`, `closing` and `closed` ready states:

They also both throw an error when a message is sent while the ready 
state is `connecting`:

I don't think there is any notion of message buffering in these specs 
either: `open` means the message can, in theory at least, be delivered

The `connecting` proposal would align the spec nicely with the two 
other specs. The alternatives you suggest would create a different 
scheme which, while better in some cases, may also confuse developers 
used to dealing with WebSocket channels. Do we need to solve a 
specific case that WebSockets and WebRTC data channels do not have?
