Hi. The use case in mind is to
 # get URI nodes NodeFactory::createURI using (or Graph::find and Triple::getSubject / Triple::getObject in case of JENA-1688)
 # process this URI nodes in different ways (nothing what could be done with a SPARQL CONSTRUCT query)
 # generate new triples and graphs using some of the processed URI nodes

The idea was to use Java type safety to enforce integrity during the process. Of course, there are other ways to ensure that. And I appreciate that you do not want change this.

> I propose to precise the return types of the NodeFactory methods, e.g. to set NodeFactory#createURI return type to Node_URI. This makes the developers life easier, as there is no longer a need to cast after creating a Node, if one need a specific node type. I can not see any disadvantages and it should be backward compatible (except of classes that override these methods).
