The RDFS-compatible semantics for OWL DL heavily depends on owl:Class (more
precisely, on IOC, the class extension of owl:Class).  If the distinction
between owl:Class and rdfs:Class was removed the semantics would be quite
different.

Test cases are rather hard to come by, as OWL DL is designed so as to
prevent one from interacting with classes that are not OWL classes.
