How would they add runtime checking without breaking all existing code?

But I think warning people is a good start, because those checks can be added to your CI pipeline and reject any incoming code that contains warnings. That way you can enforce type checking for a subset of modules and keep backwards compatibility.

By making it opt-in. But that's not much different from static typing then, except that it won't actually work when you screw up typing
