Remove send-error message about saltyrtc-meta

[ovalseven8]

May I ask what's the current state on this? What's currently happening in such a case you mentioned in this comment?

On the Websocket layer, the only solution is to send back a "acknowledge" message. Since SaltyRTC is based on websockets, it's up to the applications to ack messages. So, removing send-error makes sense, I would note in the docs though that websockets don't work like TCP in this case.

Like you said, I do not see much value to add a new field to the disconnected message. In the end, it does not matter and the client cannot really conclude if a message was received or not.

It's currently implemented but implementations should not rely on it. We still need to remove it.

You mean applications who use SaltyRTC should not rely on send-error, but implement their own ack protocol if needed?

Yes
