dnsmasq and systemd-resolved are mentioned in the paper.

In their paper they talk about IETF efforts:

but I've not been able to find any discussions on the usual DNS related 
IETF mailing lists (like dnsop).
Did you observe this topic at any IETF WG mailing list?

For a thread about this on the powerdns-users mailing list:
