go - Why golang Lookup*** function can't provide a server parameter?

Question

For nslookup command, it has nslookup somewhere.com some.dns.server.

However, it seems that golang dnsclient only load config from /etc/resolv.conf

code here: https://golang.org/src/net/dnsclient_unix.go#L225

Does the golang standard library provide something like func LookupTXT(name string, dnsServer string) (txt []string, err error) ?

requirement: 1. Don't change the default /etc/resolv.conf.
