Having some things not work is OK. Having lots of important things not work
is not OK. There are tradeoffs here and it's rational to choose a

Web developers tend to do that. Which is one reason why prefixing fails.

We might be able to get close without much work.

I think we (Mozilla) should put the non-standard names behind a pref and
put webkitAudioContext behind another pref. Then as our Web Audio
implementation marches through our release process, users and developers
can easily experiment to see how much compatibility we get by turning on
those features. If we get valuable compatibility, the argument for
defaulting on the necessary prefs is strong.
