Sorry, I don't understand this.
There is no way the class method is going to return subclasses.

Really? Don't tell that to whoever designed NSString (for example) and its subclasses. Because they return id and not a specific instance of the class, you can call [NSMutableString stringWithString:@"hello world"] and get a mutable string instead of a regular string.
