I'm surprised to hear you say that, Roy. I believe that the Semantic Web will care because one needs to be able to merge graphs without prior knowledge of what's being merged. If the target of an assertion varies as a function of the definition of the predicate, that will not be possible. Though I can't find it right now, some time ago on www-tag you suggested, IIRC, that the Semantic Web could use a function to disambiguate between when the target of the assertion was the resource vs. a representation of the resource. I believe this is a superior approach to what I interpret you to be suggesting above, as would any other approach which added additional information to a triple to license a recipient to determine what the target of the assertion was.
