Unfortunately, systemd-resolved caches far too aggressively and will
poison its cache, even accidentally.  Various parties have tried to
explain this to the upstream developers, but have not succeeded.
systemd-resolved should be safe to run behind a BIND 9 recursive server
in non-forwarding mode, but not much else (I believe even Unbound is
unsafe due to its last-resort message handling).

systemd-resolved also does not handle exotic record types, I think, it
is more an NSS-level solution than a libresolv-level solution.

(An earlier attempt in this direction is lwresd, which is part of BIND 9.)
