Why would you need that? It doesn’t make sense to provide v6 DNS server information over a v4 protocol.

SLAAC (RFC6106) can already provide RDNSS information (Resolving DNS Server) in the RAs.
SLAAC and/or DHCPv6 are completely separate from DHCPv4. There’s no overlap and there shouldn’t be any.

People who support Lorenzo’s religion are relatively few and far between in the operational community.
