The only piece I'd add to this is, I'm often taking corners at the very limit of grip. Having some negative camber likely evens out tire wear, but I don't have a baseline yet. I suppose if I lose some rear-end traction from having zero toe in at the back, I'll simply scale back the speed around corners slightly, and it'll be fine, but I'm a little wary of making the car too tail-happy. The compromise for being able to set the rear toe to zero might be a little more rear camber than front, and/or a stiffer front sway bar, so the rear is less likely to get out from under me.
