I think this is a distorted impression that comes from observing one sub-group
of RDF users. Luckily nothing in RDF itself does anything to enshrine URI
schizophrenia.

Well, I'm a hard-core RDF user, and I ask the same question. My software does
not concern itself as to what URIs mean. Luckily RDF specs do not require it
to.
I have seen these URI questions come up even when RDF was nowhere near the
picture, so again I think you came across a distorted impression (which seems
to be the same one Simon came across).
