The previous link was to "extended callable" types, which are
deprecated in favor of callback protocols. Unfortunately, defining a
protocol class can't express the typing -- we need some sort of
variadic generics[1]. Specifically, we wish to support hitting the
endpoint with additional parameters; thus, this protocol is
insufficient:
```
class WebhookHandler(Protocol):
def __call__(request: HttpRequest, api_key: str) -> HttpResponse: ...
```
...since it prohibits additional parameters. And allowing extra
arguments:
```
class WebhookHandler(Protocol):
def __call__(request: HttpRequest, api_key: str,
*args: object, **kwargs: object) -> HttpResponse: ...
```
...is similarly problematic, since the view handlers do not support
_arbitrary_ keyword arguments.
