OK, it looks like the LC-PCC policy statement for 19.2.1.1.1 restores AACR2 21.1C1c through the back entrance, at least for corporate bodies:
Applicability, 2b: Do not consider the corporate body to be the creator if there is any doubt that a work falls into any of the categories. The corporate body may be eligible for use as an access point under another instruction in RDA chapters 19-21.
