Public note

Not all consumers depend upon the same implicit interface, but given enough consumers, the implicit interface will eventually exactly match the implementation. At this point, the interface has evaporated: the implementation has become the interface, and any changes to it will violate consumer expectations. With a bit of luck, widespread, comprehensive, and automated testing can detect these new expectations but not ameliorate them.
