NCA is present and not enabled by default. But you can only use it in the global zone. It predates zones and ZFS. Probably you don't need it or want it anymore.
Indeed I am planning to remove it at a future date as I don't believe it is in use by illumos or SmartOS users and I don't think it's useful anymore.
