I've made it explicit what I believe safe means. I could discuss it in more detail, but I won't be changing my definition. I would never do such a barbaric thing as adding a non-inheritable class to an object system. Or, if I were convinced to, it would be purely for performance, not as a way of restricting the programmer; i.e. for speeding up things due to the compiler knowing that the class is final.
