Hi Lars,

I'm not sure this would be 100% safe, as multiple ways of specializing 
skos:broader can be thought of, cf ISSUE-56 [1]
And these mixes, leading to possibly confusing hierarchies for 
newcomers: consider the combination of "transitive"and "partitive" 
specializations. We can specialize skos.broader into 
skos:broaderTransitive, skos:broaderPartitive, 
skos:broaderTransitivePartitive. If we consider other axes of 
specialization (e.g. for "generic" and "instance" flavors of hierarchy) 
this would blur the picture even more...

On the other hand, given the number of reactions we had on this 
transitive aspect of broader, we might just decide to introduce only 
transitiveBroader, as an acknowledgement of the interest it gained.

Whatever, ISSUE-56 is still open, and comments are welcome!
