Offhand, I don't see any particular use for partial reification, but...

Under the present regime, I think the pain of disallowing partial 
reification (e.g. "syncing and transaction mechanism") is greater than the 
pain of allowing it.  Also, I don't see how one can prevent somebody from 
creating a model such as:

    [S] --rdf:Type-----> [rdf:Statement]
    [S] --rdf:Subject--> [SomeResource]

without the remaining parts of the reification quad.  I'm not claiming here 
that this is useful (though I do think we should be very wary of 
disallowing something because we can't see its utility), just that I can't 
see it does any harm -- it's simply a couple of RDF statements.

It seems to me that in pursuing solutions that avoid the perceived 
clumsiness of reification quads, we seem to end up with cures that are 
worse than the disease -- opening up new problems that just don't arise 
with the current approach.
