Yes, getaddrinfo is a terrible interface and getaddrinfo_a is not helping.

Unfortunately, doing a 100% functional drop-in replacement for getaddrinfo has
turned out to be a really difficult task. Several distros have through times
tried to ship curl built with c-ares for this reason, but so far everyone has
eventually had to back down from that decision because of some special edge
case where c-ares did not behave like getaddrinfo.

With luck, one future day c-ares has gotten all of those problems ironed out
and we can switch to a proper asynchronous name resolver more universally...
