My proposal was quite clear: The functionality remains experimental, default off until you can come up with a satisfactory model here. Giving the impression that I'm the one to propose a model is simply inadequate: You want the functionality in, so it's primarily you who should find an implementation that's free of (latent) security issues. While in general other maintainers may help with this, implying that if they can't suggest a suitable model code with recognized potential for security problems can go in _and_ become supported is wrong.
