Forgot to mention another point. If you load all ontology files at once you 
have an ability to "patch" ontologies to suit your needs such as specifying 
whether to do fulltext indexing for properties, providing some backend-specific 
hints and whatnot.

This way you still can customize ontologies somewhat and yet keep using shared 
ontologies package instead of dragging your own customized version along.
