This option make it easy to ignore anything about the server we're connecting to, which is bad security practice. This was necessary as we didn't use to expose detailed information about the certificate, but now that we do, we should get rid of this. If the user wants to ignore everything, they can still provide a callback which ignores all the information passed.
