Oh, and this often confuses devs when dealing with KVO dependent key trigger situations..

The reason that this is particularly troublesome is that KVO registering dependent keys only triggers notifications on the class that registered. So if you implement your safe initializer


+ (void)initialize
{
    if (self == [MyClass class])
    {
        // register depending keys
    }
}

subclasses won't trigger dependent notifications.

For the curious, the two bugs that were filed as a result of this realization (on documentation, on framework)
