* Kill off redundant SynapseRequestFactory We already get the Site via the Channel, so there's no need for a dedicated RequestFactory: we can just use the right constructor. * Workaround for error when fetching notary's own key As a notary server, when we return our own keys, include all of our signing keys in verify_keys. This is a workaround for #6596.
