The entities_starting_set is the set of entities the user originally requested to export to the archive. The archive might contain many more than the original selection due AiiDA's provenance tracking, which means that connected entities are also included in the archive (according to the graph_traversal_rules). Showing this information easily makes the output of verdi storage info unreadable (see below). The display of UUIDs should be truncated, at e.g., 5 entries max, and the full list only be shown with the flag --detailed.
