Yes the class tree needs work, especially the higher levels, and copying
someone else's High Level Ontology seems to be impractical as they all seem to be copyrighted. I hope that this is the kind of thing that will get better with time. We will see.

Freebase's is not copyrighted ! :)
In Freebase, we had the notion of a community curated mutex that applied simple rules and visually would warn a user when they applied an instance of (Freebase Type or Class) to an entity that was also typed by a mutexed Class.
For instance, Pets ARE NOT Humans And other simple things like that.
Wikidata might want to begin creating something like that. Q82955 NOT ALLOWED AS Q5 or whatever works for you guys.
The Big Mama Mutex in Freebase was the primary one and others...all of which is still in the Freebase graph data itself. Use it as a starting point if you want.
