Why should this be the general approach for schema.org?

Note that Cyc and schema.org have different goals:

Cyc is "an artificial intelligence project that attempts to assemble a comprehensive ontology and knowledge base of everydaycommon sense knowledge, with the goal of enabling AI applications to perform human-like reasoning."

Schema.org is "a collection of schemas that webmasters can use to markup HTML pages in ways recognized by major search providers, and that can also be used for structured data interoperability".

Compare the definition of "place" in Cyc with that one in schema.org:

Cyc: "A specialization of EnduringThing_Localized (q.v). Each instance of Place is a spatial thing which has a relatively permanent location. Thus, in a given microtheory, each Place is stationary with respect to the frame of reference of that microtheory."

Schema.org: "Entities that have a somewhat fixed, physical extension."

A clean conceptual foundation is in general good for schema.org, but it is not the only dimension for judging the quality of modeling choices. How well typical Web developers can grasp the intension of the concepts is similarly important. 

This is why Cyc may have the type "human that is not an infant":

Schema.org will likely not have it, at least not under that name.
