I've developed the habit of not thinking things like "how hard can it be" when dealing with semantics. The answer is generally "very".

You could well be right, but the cost of taking a stab, giving it a "W3C" URI, and getting it wrong is very high. We, as a community have done that a lot - RDF lists, reification, rdf:alt, rdf:XMLLiteral, plain literals, and probably more.
