This is already a real problem; there are shipped games out there based on
my compiler/libraries that break under modern Aurora/Nightly builds of
Firefox due to Web Audio. Any authors who don't know to pull down the
latest versions of my libraries will get broken games in FF, and will
probably break if Chrome's implementation ever changes. To the average
player or developer, it looks like an inexplicable regression - add to this
the inevitable actual bugs in implementations/apps... I can only imagine
how bad things could get if, some time down the road, the Web Audio API
gets revved again to make necessary changes, or another browser vendor like
Microsoft decides to integrate it and now webapp/game devs have more
compatibility targets to deal with.

Are there other ways we could identify uses of the old API names in the
wild? Like, is it possible to hook into search crawlers like GoogleBot or
Bing's spider, and have them flag any .js files containing 'AudioContext'
or 'webkitAudioContext'?

Is the compatibility picture just too difficult here? As a crazy strawman,
could it just be decided that as convention we want end users to load a
shim library off JS CDNs like the ones they grab jQuery from, instead of
rehosting, so that implementations can be updated as the spec evolves? I
don't even know if that would actually solve the problem, just trying to
think of some possible way we can address these issues. I want to see the
Web Audio API improved, but somehow the relatively minor tweaks we've had
so far are already causing issues, and that's unfortunate.
