We added a new argument to `client_request.get` and
`client_request.post` to specify that it should return a raw `Response`
object rather than an instance of `BeautifulSoup`.
This is useful because sometimes we need to look at stuff like the
response headers.
However it turns out we already have a separate method for this, so
rather than invent something new I think it’s better to stick with the
thing we already have.
