I think that should be an option seriously investigated. As the 'slogan' 
of SWRL is "Semantic Web Rule Language (SWRL) based on a combination of 
the OWL DL and OWL Lite sublanguages of the OWL Web Ontology Language", 
offering an OWL-Full schema would be rather inconvenient ;-)

 From a purely esthetical point names such as argument1 and argument2 
are not optimal either. Furthermore, the names do not convey the 
semantics of the properties, i.e. they do not show in what way these 
arguments are used in the interpretation of SWRL rules (as domain and 
range of predicates?).
