I have noticed similar points - a lot of reasoner based software, and 
graph internals software, and probably triple storage software will 
allow subjects as literals - but when considering systems and 
applications that actually do something useful (rather than just the 
internals) then you interface with people, and the difference between a 
literal and something else is crucial. This is where I see the costs.
