>Mercurial, made by another (in my opinion) much more well-spoken kernel hacker, is what really introduced me to the concept that you do not break interface for downstream users, no matter how wrongly you may think they are using the interface. It matters less, IMHO, the further up the stack you get. Being right at the bottom of every stack it matters most of all for the kernel, which is why Linus needs to be such a stickler. The amount of damage you can do by breaking userspace is vastly greater than the damage you do removing an hg command.
