Personally, the sooner the Nouveau people throw in the towel the happier I'll be. Yeah, I get that it scratches an ideological itch, but it's crap. What good is hardware I can't use? Nvidia's drivers and software stack are top notch and always just work.
They surely work... under X. But what are they doing to support Wayland for example? Or MIR? If it weren't for the nouveau drivers there would be absolutely no way to test these new technologies with nvidia cards.
