In other words, it is much easier and cleaner to override how Curl_ipv6works() to adjust to demands of certain systems/scenarios than do checks if "IPv6 works" and change resolve mode in every place where application sets a transfer.
Maybe you could contribute your system-specific IPv6 detection code as patch(es) for libcurl? This approach would not require any new callback.
