How can polling approach that somehow monitors currentTime meet any
halfway-decent accuracy requirements? E.g. to be accurate to 1-3 samples
at 22050 Hz sampling frequency? I doubt your approach could fulfill this.

To my mind, the current turn of events suggests simply to allow
start/end attributes back into the WHATWG spec, eased by the fact that
there were already browser implementations of it.
