There may be multiple reasons for a webRTC endpoint to cease transmission
(one being circuit breaker) and I feel we should not add all those here in
consent draft.

Also the the above statement indicates a need for a new API to notify the
application about the loss of ability and this is some thing outside the
scope of this document.

IMO this text looks out of place and we should not add this to draft.
