In general, that's an apt description for DRAKON proponents. I interacted with them more than once.

And at this point, it's not even clear if DRAKON charts make sense even for their intended purpose: visual illustrations of simple algorithms. They are better than classic flow charts, but that's mostly because flow charts themselves are hopelessly bad.

Sequence diagrams are better to show interactions between agents, and good old state diagrams are far better structured to visualize state transitions.
