Supporting type imports

I am currently working in a Python project with strict mypy typechecking that requires functions to be fully typed. In order to implement the before_send callback, I need access to the EventProcessor, Event, and Hint types in order to properly annotate the function’s signature, like so:

def create_handler(exceptions_to_ignore: List[Type[Exception]]) -> EventProcessor:
    def before_send(event: Event, hint: Hint) -> Optional[Event]:
        if "exc_info" in hint:
            _, exc_value, _ = hint["exc_info"]
            if any([isinstance(exc_value, exc) for exc in exceptions]):
                return None
        return event
    return before_send

However, all three of these types are defined in sentry_sdk._types, and the leading underscore implies I should not be importing from that file. Are there any plans to make these (and other) types part of the public API? At the moment, I am forced to use extremely permissive types (like Any), which means my code can’t be statically checked by mypy for correctness.

Event is currently Dict[str, Any], which is not wrong, but if we changed that to be a TypedDict, before_send’s return type would stop typechecking for some people.

That’s a very simple example. We may also just say that type hints are exempt from semver. Not sure.
