Nameservers that are not DNSSEC aware will not get responses that
contain DNSSEC records unless a client explicitly requests a DNSSEC
record type or make a * (ANY) request.

There is no problem to solve.  Just a lot of misunderstanding.

That said the majority of nameservers on the planet are DNSSEC aware
and will request the DNSSEC record to be returned.  They will also
fall back to plain DNS if middleware blocks the response.
