WebGL 2.0 uses OpenGL ES 3. We should be careful that code that uses gl.getExtension to query WebGL extensions does not break. I'm not sure how this will be dealt with in the WebGL 2.0 spec, but I think if something was an extension in WebGL 1.0 and is no longer an extension in WebGL 2.0, gl.getExtension should still return the same value to ensure backward compatibility. see https://bugs.webkit.org/show_bug.cgi?id=133636

iOS 8 Beta 2 still does not alleviate the artificial constraints.
