nsd users - Mar 2018 - support for draft-bortzmeyer-dprive-resolver-to-auth

Hello unbound+nsd developers,

not sure if you're aware of
https://datatracker.ietf.org/doc/draft-bortzmeyer-dprive-resolver-to-auth/
Do have any ideas if it's possible to implement such stuff in future unbound
and / or nsd releases?
