I once tried to add a feature to Windows (back in the sd days), and it was a nightmare. I was in the C&E org so it was a side project thing, and I eventually postponed it (but then left MS so never got it finished). I imagine it's gotten much better since then, in large part from the shift to git alone. It certainly was super impressive feat for the shear scale and longevity. I have a lot of respect for the folks who make that beast work. And there are bits of it that are brilliant. But it was an ugly beast.
