This story and the previous one (finally removing the BKL) are making me happy. These are potentially serious, scary changes that Linux's development model just skis right over.

Stable driver interface? If Linux had one, these changes would be close to impossible. And, if you're still unconvinced, take a look at what Microsoft's DDK has turned into.

Yeah, the entire MS business depends on backward compatibility. Check Raymond Chen's book 'The Old New Thing' for really fun stories of the great lengths MS developers go to maintain such compatibility.

Also Check the mentioned book 'extras' online chapters on the publisher's page, where the author maintains backward compatibility for Win3.1 games in his youth days. At the time where hardware protection wasn't used by Windows and the code Windows was trying to be compatible to was doing amazingly silly stuff with the x86 processors and PC architecture nuances (GDT, IDT, PIT, etcetera).
