I would expect most applications to use only AI_SECURE_CANONNAME or AI_CANONNAME_SEARCH_DEFAULT. AI_CANONNAME_SEARCH_DEFAULT would come with a system-wide knob attached. But perhaps we should just say that AI_SECURE_CANONNAME should behave like what I called AI_CANONNAME_SEARCH_DEFAULT. Some applications might offer app-specific configuration knobs to specify the use of any of the other AI_CANONNAME_SEARCH_* flags. _Most_ apps would not. The availability of choices at the API level != a plethora of application knobs, just the possibility thereof.
