This is a question for typing-sig.

Over on typing-sig we are looking at alternatives to Callable, so it's
unlikely that any changes to Callable itself will be accepted.

Instead of `...`, we will probably use `*args`, similar to what is used in
the `def` syntax.

Feel free to peruse the typing-sig archives to learn more about the current
status:
