Hopefully somebody else can supply these.

Any application that aggregates people's comments about propositions.  In
fact this was the origninal test case that was presented way back ~ 1999 in
the rdf-interest group - if i get a chance I'll try to find that original
test case.

If the WG chooses to allow distinct multiple descriptions of RDF triples,
what specific future apps would become impossible?

It breaks aggregation of annotations of triples.
