Since supportsContext is not supported in Safari on iOS, authors cannot use it to detect this case at all. We could say in the spec that if a UA knows it cannot create a specific context, it must hide the corresponding interface object. This does basically the same thing as supportsContext, except that it would also work for pages that already do feature detection based on the interface object. -- Simon Pieters Opera Software
