C# shows pretty compellingly that adding features does not have to break existing code. For example, you can use every keyword added after 1.0 as identifier, too.

But it can make things more complex too. e.g. I recently learned that the main reason that asynchronous C# methods have to be declared "async" is so that the compiler knows that in the method body, "await" is a keyword. Without this backward compatibility requirement, it could be inferred from the return type + the presence of 1 or more "await" keywords.
