agreed.
The custom DNS stub resolvers that I know about (adns, ldns, libevent) reimplement the libc resolver, with their own parsers for /etc/resolv.conf and all the rest.
dns requests should almost universally go out via the open source "getdns" API (https://getdnsapi.net/) at this point. if your code uses one of the above methods, or getXbyY() in any form, please investigate.
