I tend to like long term stability in who things are done, but I'm  
not stuck in the mud,  the point of my email was to reassure someone  
that in fact a 1-stage build will never go away, exactly how one  
achieves that I don't care as much about, only that it be possible.   
I have two trees (actually 83 trees to be precise, but whose  
counting), one that only bootstraps and one that never bootstraps, so  
I am fine with it being a configure option.
