The conclusion to draw from this is that the hypothesis "the only thing in a document should be layout information not arbitrary code." is wrong and misguided, since whatever the format is, in the end "nature" (us) will make it evolve in a way that has some amount of arbitrary scriptability ; if it's not JS in PDFs it will be ActiveX controls, a government-mandated proprietary app, having to do a trip to the city hall to have the clerk play an algorithm step-by-step by hand, or something else, but something will always eventually come up to fill that void and you will have to use it whether you like it or not.
