Stable APIs are not strictly an engineering problem, it's also a business problem. In fact, most of the engineering that occurs is due to business problems. Most of the instability around software engineering comes from business requirements - they pay engineers to do things faster/less errors/better. So we ditch the old version and build new ones. And the world goes round.
