Wikidata statements are not binary, and values are not untyped. However, there is the concept of “simple statements”, especially in conjunction with the RDF exports (although not untyped, these data usually look like binary relations). Indeed, any statement can be annotated by a list of “qualifiers”, each of which can have zero or more values, can have references (which can have their own qualifiers) As for types, “GlobeCoordinateValues”[0], i.e., locations, form one of the types allowed for values, and consist not only of two integers, but indeed of four distinct values: latitude, longitude, precision, and the reference globe, since Wikidata does not limit coordinates to the Earth. There is also no “massive proliferation”, the data model[1] knows 12 types[2], of which four are four different kinds of texts (untranslated, monolingual, multi-lingual, and list of multilingual texts).
