OK, this part requires further thought on my part,
so I will not respond further here ...

But this is a draft specification, subject to continual
improvement, and if the WG were to decide that this
behaviour is sub-optimal, then it would be perfectly
possible for a future draft (and, perhaps, the final
release) to specify that turning off audio and/or
video /should/ cause the contents of the corresponding
elements to be rendered.
