The auxiliary pan drain line could go no where and there could be a cut off switch in the pan instead.
I personally like to see both the auxiliary drain pan drain line *and* the cut off switch.
Ted, who you trying to kid about homeowners recognizing that water dripping in front of the window as meaning the a/c needs servicing?
That's the reason for the cut off switch also - when that drain line clogs up, the cut off switch shuts the unit off (if the switch works - which is why I also like having the drain for the pan, each one acts as a failsafe for the other).
