Some RDF databases use the fact that the number of different predicates will be small compared to the number of different nodes in the subject or object position as a source of optimisation. Allowing blank nodes as predicates, though it would be convenient and in some respects more elegant would tend to break this assumption to the detriment of the databases that are affected. This is a very real concern. Allowing blank nodes in the graph position would not, as far as I am aware, have a similar impact on existing implementations. My impression from the previous discussion is that it's an easy patch to the standards documents as well.
