Please add nslookup, host, dig as part of the base os and not part of option 31, dns

I need to use nslookup (could maybe settle for dig or host) from IBM i. However only my lpars with option 31, dns, loaded have that command. I feel that option 31 dns is a 'host' feature while nslookup, etc are client features. I do not want to load option 31 because that uses an ancient version of bind and caused me to fail audits. I've already submitted RFE's to use newer versions of bind and IBM says they have no intention of doing so and will just continue to PTF dns and only change the version of bind to one that's only a few years behind at a release level.
Please add nslookup to systems without option 31, dns.


Use Case:

I am using HA Replication software and during a switch I need to verify dns lookup without having option 31 dns loaded.

    The NSLOOKUP, HOST, and DIG commands will not be converted to use the IBM i Resolver APIs in the OS base. The Option 31 provided NSLOOKUP command can be used without configuring or starting the DNS server. If the server is not started, an external audit/scan of ports should not fail because option 31 is installed on the system

    The HA application in the use case can code to the IBM i Resolver APIs or getaddrinfo() to do a name resolution directly. That does not require Option 31 be installed. Refer to the API documentation in Knowledge Center for information on these APS. https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_72/apis/unix8b.htm

    IBM i option 31, as Jan 2017, has BIND version 9.10.1 available on 6.1, 7.1, 7.2 and 7.3.
