--- Comment #1 from Martin Thomson <martin.thomson@gmail.com> ---
Note that the mutable attribute was not popular.  There was a general
preference for a setter.  The primary reason being that the replacement might
fail.

I think that the general sense was that failure was not a problem that browsers
need concern themselves with: the track would simply go BYE-BYE (i.e., RTCP
BYE) if media could not be provided in a compatible form from the new source. 
However, it was observed that replacement would not be atomic and that maybe a
promise-bearing method was superior.  That would allow for the time of
replacement to be marked, as well as giving the application a way to learn
about errors.
