noExtensions requests that it would like the underlying system to turn off as many extensions as it can. Like depth, stencil and antialias this is a hint, not a requirement. WebGL sets this to true hoping that the underlying OpenGL ES implementation can turn off things like OES_texture_npot thereby not requiring WebGL to enforce it itself. Of course WebGL still has to check the extension as turned off
