I've submitted PEP 591 (Adding a final qualifier to typing) for discussion to typing-sig [1].
Here's the abstract:
This PEP proposes a "final" qualifier to be added to the typing
module---in the form of a final decorator and a Final type
annotation---to serve three related purposes:
- Declaring that a method should not be overridden
- Declaring that a class should not be subclassed
- Declaring that a variable or attribute should not be reassigned
