No. The proposal has no such semantic consequences for the class 
owl:OntologyProperty. I only proposed to make a few specific
ontology properties into annotation properties, *not every* ontology 
property. The proposed change is as small as possible to just get
the described problems fixed, it's not meant to be a change of 
the "parts hierarchy" in OWL (2) Full. (Technically, the only consequence
is that the classes owl:OntologyProperty and owl:AnnotationProperty
cannot be assumed to be disjoint anymore -- who cares?)

Yes, the term owl:OntologyProperty will still exist, and so will 
probably still be mentioned in QRG (for those who care).
