A very simple use-case that we frequently face in e-commerce:
Sites do have category information (sometimes even based on standard categories), but they are unable to include the authoritative URI of that category in the page markup, e.g. because it is simply not in their back-end database or because there is no simple translation from what they have in their database to the URI.
A typical case are shop categories. Sites often do have a notion of product category, and even an hierarchical ordering, but they are unable to match that to the URIs of respective standards with reasonable effort.
Having a SKOS-like mechanism in schema.org allows a site to expose its proprietary hierarchy and preserve the links from products to it. A search engine or other client can then try to consolidate categories across sites at consumption time.
Let site owners expose as much data structure and semantics as they have available, but do not force them to lift the data to ideal heights... ;-)
