[whatwg] Implementation difficulties for MediaController

It's been brought to my attention that there are aspects of the
MediaController design that are hard to implement; in particular around
the ability to synchronise or desynchronise media while it is playing
To help with this, I propose to put in some blocks on the API on the short
term so that things that are hard to implement today will simply throw
exceptions or otherwise fail in detectable and predictable ways.
However, to do that I need a better idea of what exactly is hard to
It would be helpful if you could describe exactly what is easy and what is
hard (that is, glitchy or simply unsupported by common media frameworks)
in terms of media synchronisation, in particular along the following axes:
* multiple in-band tracks vs multiple independent files
* playing tracks synchronised at different offsets
* playing tracks at different rates
* changing any of the above while media is playing vs when it is stopped
* adding or removing tracks while media is playing vs when it is stopped
* changing overall playback rate while a synced set of media is playing
Based on this I can then limit the API accordingly.
(Any other feedback you may have on this proposed API is of course also
