We could achieve this by rewriting the processOperation method, but that would require recopying the entire DenseAnalysis. Maintaining a separate copy just for this minor feature would be quite costly. Furthermore, it's common in dense dataflows for most operations to have no relation to dataflow iteration; this isn't a custom requirement.
