PDF ISO-32000 has a note in clause 12.6.2 that is just dying to get the PDF/D Best Practices treatment:
"Conforming readers should attempt to provide reasonable behavior in anomalous situations. For example, self-referential actions should not be executed more than once, and actions that close the document or otherwise render the next action impossible should terminate the execution sequence."
How about insisting that the Next entry in Action dictionaries shall only contain acyclic graphs of actions? When would endless loops of action sequences ever be a good thing?
