My experience suggests that reification is a very useful feature. Here are some additional usage notes. In my research prototypes developed in Stanford, I use reification for representing order and aggregation in RDF. I also added a pair of parser/serializer to the RDF API that uses a very simple, stream-oriented XML syntax that supports concise serialization of reified statements. Whenever I utilize reification, or need efficiency, I rely on edu.stanford.db.rdf.syntax.generic.TripleSerializer / TripleParser instead of SiRPAC and M&S 1.0 RDF/XML serialization. As to industry, Last Mile Services Inc. is using a relational engine for managing RDF datasets with full reification support. Additionally, the company is working on an SPKI-like security model, in which reification is used to assign cryptographic signatures to pieces of RDF.
