Sure, why not. I see your point, and agree that it should be care of the scripter ensuring there is a party. But if this is the case, it should be clearly stated in the documentation.
Generally, our documentation sucks because scripters never knows those things by reading the manual, and have to learn by trial and error (and some times, the error doesn't always show up, depending on what they're doing, so they learn terrible practices because we don't teach them better in the documentation).
