Why not "Pan-"?

We then added a standard suffix (“-morpha”) to the crown names to identify corresponding total clades.

I think these are excellent definitions. However, I am curious as to why the authors invented a new convention for total clade names (the suffix "-morpha") instead of using the one recommended by the draft PhyloCode (the hyphenated prefix "Pan-", which would have yielded names such as "Pan-Cetacea", "Pan-Artiodactyla", "Pan-Suina", etc.). I know there are existing total clade names ending in "-morpha" (e.g., "Carnivoramorpha", "Archosauromorpha"), but there are also existing names ending in "-morpha" which are not best applied to total clades (e.g., "Nematomorpha", "Lagomorpha", "Seymouriamorpha", etc.).

Competing interests declared: I am currently a member of the Committee on Phylogenetic Nomenclature, the governing body for the PhyloCode.

(Slight correction: Carnivoramorpha is actually not a total clade, since it excludes creodonts.)
