if its design is good, then interface can be changed in a moment without any problem
This isn't always the case. Sometimes the interface puts requirements (contract-like) upon the implementation. Case in point in the kernel, dnotify versus inotify. dnotify is a steaming pile of worthlessness, because it's userspace interface is so bad (meaning inefficient) as to be nearly unusable. inotify has a different interface, one that supplies details about events rather that mere notice that an event occurred, and therefore has different requirements in implementation. dnotify probably was a good design, but for a worthless interface. The interface isn't always important, but it's certainly something that has to be understood before putting the finishing touches on the behind-the-scenes implementation.
