FWIW, WebKit uses the audio track availability and Blink intends to do

There are fundamental technical issues to resolve before this can be
achieved. And at this stage, I'm not convinced it could ever be
achieved, nor if that's worth it.
It would likely require spec changes
The media element play() has synchronous steps required, while the
entire playback demuxing/decoding steps are fully asynchronous. We can't
reliably determine if a particular track is available in a synchronous
fashion before the play() steps complete. If MSE is in use that becomes
even more tricky.
