After reloading all bibs and authorities for the RDA upgrade, we have a number of authorities with the 667  THIS 1XX FIELD CANNOT BE USED UNDER RDA UNTIL THIS RECORD HAS BEEN REVIEWED AND/OR UPDATED.

The list I have comes from an III blind headings report and is all uniform titles. I imagine there are other types of authorities with the same message.

My question is: Should I ignore this 667 message and change headings in bib records to match the authority?
