There is a long history of browsers disabling or crippling features because they get abused by web pages. In fact is is almost a rule that if a feature can be abused, it will be abused.

A possible solution is having a "responsible app mode" in browsers. Whitelisted webpages have full access to these privileged APIs which would otherwise be stubbed out and non-functional (hopefully in a way that a webpage can't detect).
