You're missing the crucial part: grsecurity is not a company with deep pockets. There's little to no incentive for them to spend time on doing something, somewhere they're not terribly welcome. :) Yeah, I'm exaggerating Linus' involvement. But for me there's always personality stink around projects this size. And it's obviously not different for grsecurity itself or, say, OpenBSD. But this definitely has some major upsides too. Basically what I'm trying to say is that even this over the top image of Linus-the-Destroyer should not be read as negative. Everything is shades of gray. Having said that - there's a history of clashes between prominent Linux devs and grsecurity. At this point anyone (Linus or otherwise) would be more than justified shying away from any cooperation with grsecurity. At the same time this doesn't prevent active developers with commit rights from cherry-picking changes (which happens).
