Plant Patent cpcs

I found that more than 13,000 plant patents on uspto.gov have been assigned cpcs! (cpc=Cooperative Patent Classification) I don't recall seeing the memo saying that plant patents could receive cpc assignments. This page is asking patentsview for data on those same plant patents. The results below show that patentsview does not send back uspcs or cpcs as they should. I've turned the patent numbers into links that will bring up the patent on uspto.gov where these fields are present. Apparently the patentsview people did not receive the cpc memo either!

The cpcs shown on the uspto pages are the cpcs when the patent was issued. The patentsview api uses the current cpc file provided by the uspto, the U.S. Patent Grant Cooperative Patent Classification (CPC) Master Classification File (MCF). This file only contains cpcs for utility patents. It does not contain cpcs for plant patents or reissued patents as it should.
