Frederick, I whole-heartedly agree with your concerns, but please note that
the usual process of developing web standards will only work if the browser
engines implementing the experimental spec do treat that as experimental
technology that is subject to change.  WebKit doesn't do that, and for all
intents and purposes treats webkitAudioContext as a standard feature which
should never break backwards compatibility, and unfortunately Blink has
adopted the same policy regarding webkitAudioContext.  The current Web
Audio spec is full of things which are clearly bad ideas (alternate names,
numeric enums, AudioBufferSourceNode.gain, using creator methods on
AudioContext instead of constructors, etc.), but we cannot break them
because of this reason.  What we're trying to do is at least keep the API
free of footguns such as data race issues, but the way I see things, with
the current state of matters, we don't have a good pathway towards fixing
most of the API issues in Web Audio. :(
