DNS already has opportunities for caching external to ldirectord: you can run a local caching resolver with appropriate TTLs or you can run nscd. It seems like a lot of added complexity for something which could be solved already in another way. I suspect any site requiring the level of control this option provides will have the ability and experience to know how to handle the DNS lookup problem via a local caching resolver or nscd. If this option isn't enabled it becomes a non-issue as the DNS code never gets called.
