Root on lookback (RFC 7706)
---------------------------
Knot Resolver developers decided that pure implementation of :rfc:`7706` is a bad idea so it is not implemented in the form envisioned by the RFC. You can get the very similar effect without its downsides by combining `prefill <mod-prefill>`_ and `serve_stale <mod-serve_stale>`_ modules with Aggressive Use of DNSSEC-Validated Cache (:rfc:`8198`) behavior which is enabled automatically together with DNSSEC validation.
