* Allow path parameters to have default values (e.g. `None`) and discard them instead of raising an error.
    * This allows declaring a parameter like `user_id: str = None` that can be taken from a query parameter, but the same *path operation* can be included in a router with a path `/users/{user_id}`, in which case will be taken from the path and will be required.
