lwresd is in fact a full service resolver, though it is designed for
forward-only usage. Although its man page says it is "stripped-down", it
is in fact just the normal named binary running in a mode with a simple
canned configuration that gets its forwarders from /etc/resolv.conf.

AIUI, lwresd was originally conceived to deal with the original IPv6 DNS
support (A6 records and binary labels). It would need quite a lot of
re-working in the lwres client library (and possibly also the lwres
protocol) to provide proper DNSSEC support.
