 I agree with most of this, especially the part about "limiting the scope
of compatibility-affecting changes for the unprefixed AudioContext to those
that are either trivial or essential".  The "races" issue for AudioBuffers
I do not agree with.  We can't be in a situation where we're
copying-data/duplicating/neutering large PCM data buffers each time we play
a sound.  These buffers are often quite large, and it's common to
re-trigger the same sound (from the same buffer) rapidly in succession for
game sound effects, synthesizers, etc.
