Apple has taken an interesting middle approach on WebGL. They are only enabling WebGL to certified experiences in iOS. That happens to be ads for now, but it would be easy to extend this to other apps distributed through App Store. That way developers have access to WebGL as an API for 3D, but Apple is not exposing the WebGL attack surface to the entire Internet. As the spec matures, GPU drivers are hardened, etc. they always have the option to open it up more.
