One of the benefit of SPARQL is that you can extract a subset of a given dataset as RDF. And can inject it into another RDF graph. Eventually, you can build-up your dataset by picking subsets of other datasets, and link your own data graph with all that. (The top of the top is to use SPARQL federated query, so you can do all that a query-time). If you consider SPARQL as a way to implement REST API, it is the most flexible API a data producer can provide: you can run whatever query on my dataset, I force nothing. What I see as a failure in the SPARQL ecosystem, it is the lack of SPARQL query repositories for all public datasets. I tried to develop a tool for that (cf datao.net) but it never took off.
