jan-ivar has just created a new issue for https://github.com/w3c/webrtc-pc:

== pc.removeTrack(receiver) should throw an error. ==
would according to the spec not throw an error, as it would appear to get past this argument validation the [removeTrack](http://w3c.github.io/webrtc-pc/#dom-rtcpeerconnection-removetrack) algorithm:

 1. Let *sender* be the argument to removeTrack.
 2. ...
 3. ...
 4. If *sender* was not created by connection, throw an `InvalidAccessError`.

because a receiver is technically created by connection. It instead gets kicked out by step 5:

 5. If sender is not in senders (which indicates that it was removed due to setting an RTCSessionDescription of type "rollback"), then abort these steps.

which means there's no error. I think we should throw an error here, to catch this mistake, to help people grok the model.
