You would never be required to add type hints to your own code. I
guess other projects could decide they will only accept contributions
that pass the typechecker - but you don't have to contribute to such
projects if you don't want to.

At least that's my understanding. Personally, I doubt I'll ever use
type hints, any more than I use tools like flake8. They don't suit the
sort of code I typically write.
