No, I don't think it does. This is a semantic issue, not a syntactic one.
When you stick IDs on something it become reified in the graph. However,
semantically you want it to be clear that you are still asserting something
yourself, while at the same time you want to make comments about that
assertion. For example if I say:

    :Robert :likes :Cheese .

I'd like to assert that. However I also want to say that I first heard this
from :Wendy -- which means that I must reify the statement, and thus, no
longer assert it. This is not an obscure example -- this feature is
necessary for any use of RDF in a large distributed application.
