Why heirarchical taxonomy? Linnean system vs. Phylocode?

Personally, I think people had been using the phylocode system unconsciously. I think most workers are just happy to refer to a taxon just by its name without any attempt to force a neat 'Linnaean' rank into it. Dictyoptera, for instance. It's the name for the clade of termites (Isoptera), cockroaches (Blattaria), and mantises (Mantodea). Some regard Dictyoptera as an order, while the three groups are suborders. Others retain the traditional ranking of Isoptera, Blattaria, and Mantodea as orders, elevating Dictyoptera as a super-order. This in itself is problematic because Isoptera is nested within Blattaria, therefore making a paraphyletic Order Blattaria. In the end people just forget the ranks and use the names.
