That's all well and good, but I certainly wouldn't expect "nslookup
gmail.com" or for "nslookup google.com" to return SERVFAIL


If you set the CD (checking disabled) in the request, a response that
would normally be SERVFAIL due to DNSSEC validation failure will
return with the non-authenticated answer.  With dig the flag to add is
"+cd".  I don't know if there's an equivalent for nslookup.  For
example:

dig +cd @8.8.8.8 google.com
