The point (that is, the thing that matters, which admittedly you would have to actually read the thread for understanding) is that libreboot isn't available on enough platforms to be a free alternative to proprietary boot methods for most people. And that's even including all the chromebooks in the world. But Someone Is Wrong On The Internet, so I guess you can claim to have fixed that.
For, what, a handful of old laptops? It's not a general solution for libre booting.
