Wikipedia's is, for lack of a better word, shallow and says nothing about a case.

And it's not just the name of a case. Many languages handle cases differently. Latin doesn't have prepositions governing the Dative, while Slavic and Germanic languages -- those that still decline, i.e. German, Icelandic -- do indeed make heavy use of governing the Dative with prepositions. Really, rather than making up a new case, it's much smarter and less time consuming to find one that has the most common similarity, and work with that.
