Just one last one on this, then I'm hoping this tangent ends.

I think what Thierry said is exactly what Dims and I were saying. I'm 
not sure how that turned into
the idea of supporting committing broken code. The point (at least mine) 
was just that we should
not have the mindset that HEAD~4 committed something that we realize was 
not right, so we
should not have the mindset that "someone might have deployed that 
broken behavior so we
need to make sure we don't break them." HEAD should always be 
deployable, just not treated like
an official release that needs to be maintained.
